I found this episode okay. I liked the premise of Grampa's previously unknown past as a hamburger joint worker coming back as the co-founder of their 'Try It Out Burger' bar from 50 years ago comes back & reconnects with him, revealing to be the billionaire owner of a conglomerate, and it opened up for some interesting satire on corporate politics, but I never really got into it that much. It felt like it rehashed a lot of things we've seen before, the big corporation jokes felt very specific with the reference and parodying (of 'Succession' which I've never seen & barely heard about) & it just felt kinda bland despite some moments that were intriguing. I did like the Grampa & Lisa bonding and there were some nice moments here and there, the guest star performances were solid & the ending I liked, but as a whole it really didn't work as well for me as I had hoped (but I see how it was a success to some).
The opening flashback to 50 years ago (which would be 1972) with Krusty as a failed standup comedian was pretty good (and I liked the joke about someone criticising his lame joke with a question of how his humor is supposed to end the war) & it had a nice lead-in to the hamburger bar story, with Krusty stopping by Try It Out Burger and being met by this Gus character: It set up the backstory of the burger bar quickly and naturally with the dialogue (and John Lithgow did well in the role as Gus) & I enjoyed the plot point of Krusty stealing their idea and starting up his own burger bar and making it a chain (Krusty Burger, obviously), that was some nice "lore" (of course Krusty took the idea from someone else, especially when in a beat-down, bitter state). It was a promising beginning that made the following parts of the story actually really intriguing (especially after the terrible 'Burger Kings', a bad burger story).
I enjoyed the Simpsons going to the burger festival and there were not only some fun little gags (maybe especially Homer buying loads of 25 cent burgers before him and Bart are attacked by a swarm of pigeons) but I also liked the start of Grampa (angry about something in the past) and Lisa (who's skeptical of the veggie burgers) sitting down to bond a bit due to their collective sourpuss mindset (amusing). The comeback of Gus (real name Augustus Redfield) was an interesting turn, with him being a billionaire who's returned to ruin Krusty by buying his parent company which costs the clown everything (Krusty was such an asshole yet again that he deserved this) & the takeover with Gus buying everyone's acceptance by lowering the cost of the 25 cent burgers by one cent was a kinda funny moment (though Krusty getting destroyed has happened before so it felt pretty obvious it would not last all too long in the end).
Grampa's reunion with his old partner Gus also had a good start, with the latter wanting to make up for lost times and inviting him to sit among his board of directors (and Lisa get to come along as her and Grampa have already connected by now). Nice second flashback of the starting rivalry between Krusty and Gus & Grampa (I wish they'd have more with that) and nice joke of a jelaous pathethic Homer trying to convince Grampa he has a bond with him. I enjoyed the song by Lithgow (not the greatest song in the modern era, but I still liked it) but I didn't really care for Gus's three adult children whom despite being well voiced by the guest stars they didn't do anything for me, I actually thought they were kinda bland and annoying to be honest. This was also where the episode started to falter some for me and things got less interesting (maybe due to heavily leaning into the parody aspect a little too much)
It never really felt they did much with Grampa spending time reconnecting with Gus (speaking of which, it felt too soon to do another billionaire plot after 'Portrait of A Lackey On Fire') albeit I like the bit with them watching Krusty's non-copyright infringing attempt at a new show (which was an entertaining little gag scene) & Lisa developing a friendship with the daughter was intriguing, but it felt odd to see Lisa not being skeptical at all (these are billionaires and there are no good billionaires) and her being easily manipulated by the daughter and used as a pawn (in a plan to kick Gus from the company so that the daughter can take over and make it a green company) just felt a little off to me: Yeah, I know Lisa can be really naive, but I expected more skepticism and not accepting it (more or less) so fast, especially as the daughter pretty much openly revealed that she was a shifty and morally questionable person (wanting to go green or not). Despite being lured in with bribes I would think Lisa would have had more questions than she did.
I think it was the heavy parody aspect that made it feel way less interesting starting this second half, since there were a lot of jokes about how obscenely rich and spoiled this family is and none of them really stood out as all that good or great but most felt sorta lame, but none of them really that bad either but as I have never seen or am interested in seeing 'Succession' (petty conflicts and squabbles of billionaire families aren't my thing) I think a lot went over my head (and like I've said about full parodies before, they should be able to stand on their own even if you haven't seen the source material), but still, none of the jokes or supposed funny moments reall worked for me either way and more or less just felt like they were there and did their job, nothing more. I dunno, I think they could have made things more clever than just these incredibly straightforward, obvious jokes and gags about this absurdly rich family
Then we have the with the Redfield family, board of directors and Grampa & Lisa present about to decide the future of the company. I didn't care for the pointless cameos by Angela Merkel or the Literally Who? TikTok star (seriously, why?) but I actually did like the twist in that Grampa had always been used as a pawn by Gus to reveal the Redfield kids' plan for company takeover and oust them (as Grampa is on his side and give him his support, instead of voting him out). Grampa firing back by playing senile and mentally impaired to make his vote null and send the company into chaos before him and Lisa leaves was kinda clever, but I think the stuff in the background was almost a little too convoluted with the workings & going of the company (I don't even get what Grampa was supposed to get out of it all). Anyhow, Grampa & Lisa's conversation on the bus was a nice ending (Oh, and the credits scene of Krusty having found peace at a kibbutz but called back into action now with Gus' scheme revealed was fine. Felt like they forgot about him).
So all in all, the episode didn't capture my interests all that much and felt more or less just there. The first half had a lot of promise, I liked the premise and Grampa's friendship with Gus and there were some nice jokes and moments throughout, but I think it felt unoriginal (taking inspiration from past episodes (Billionaire with bad intentions, backstabbing siblings, etc.) and leaned too heavily into the parodic aspects (of a show that I, again, haven't seen or barely heard of before) and forget to tell an engrossing and intriguing story, almost making things a little too complex and nonsensical in the end. I still liked things like the Grampa & Lisa scenes and the vocal performances of the guest star (even if Lithgow's character was the only one who stood out), but I just couldn't get into it, especially when it entered its second half with the questionable moments, jokes, references and cameos). It was still an okay one, I guess.
3/5. The first half of the episode & the Grampa and Lisa scenes & some good guest performances and decent jokes were the highlights, but it still wasn't all that good to me. I get why some were really into it, but as a whole it just wasn't for me (had the second half relied way less on specific parodying and more on strenghtening the plot, it could've been really good, but as it stands, it's at least halfway decent so not a terrible episode at all, just falling short of its potential).
