This was a pretty good and even unique episode, in the way that it is both a flashback and a traveling episode. Its good to see the Flanders family (even Maude) being used for most of the episode, while at the same time there's plenty of interaction with Homer and the other family members, even Maggie. I liked the couch gag, a good use of Disney animation with the Simpson characters. And then when the show turns back to their regular animation, it looks rather stale in comparison
The episode starts out rather good and cute, with Maggie giving some good moments like not wanting to go sleep and Homer visiting the drive-in. I liked when Maggie poked Homer's eye to open itself. Then the first act continues with volunteers cleaning up a poor side of town. One interesting thing thats easy to miss is the Batman vs Superman parody poster in the background, which is now named ''Batman vs Batwoman'' and uses the same poses. There were some good jokes like "if you were homeless, you'd be home by now" and Helen not wanting to go with the Flanders. Not a fan of the joke with Lenny accidently getting injected, the interaction between Kirk and Hibbert had its moments. Overall this first act has been decent with some much needed Ned/Lovejoy interaction and even Homer complaining.
The arrival at their new destination did not... arrive with a good joke aswell. Homer visiting the bathroom dragged on for to long. I do like the touch with the bear wanting to visit the bathroom, because when you look back to an older episode then Homer made a remark that bears get to take a crap where ever they want. But now in both cases they have been doing the polite way of dumping their feces. I wasn't a big fan of the fight between Homer and Bart either. The episode does get better with the Flanders family stepping on screen, showing some Maude characterisation where it seems she's judging Marge on Bart's behaviour. Homer's snoring gag was decent. Alright now what shall I say about the gag with Homer and Bart's butts on that walkable ceiling thing.... gotta admit it was pretty funny. The new guide was a pretty fun character and even Homer's mule actually had some characterisation. The guide falling over the ridge, and that other climber who fell down and had a lot of rocks fall on him felt to Scully-esque for my taste. The episode got more interesting without the guide though.
It was fun to see Homer and Ned on a walk, but then having the billionaires club being set up as the antagonist felt a bit unnecesary if it was going to be this easy for them to steal food. There weren't really much good jokes involved with them either, some of their technology like the drones circling around the birds didn't feel like they belonged in that timelime. Even if its technically only 2 years ago, The Simpsons timeline has been halted a lot earlier. The trip on the rubberboat had some good interaction between the two, and I liked how the episode ended with Ned joining into the conversation, and later on visited a stamp museum.
This was quite a good episode, and much needed after quite some mediocrity. There are certain places they could've done better, but for most of the part they succeeded in making it a fun episode. Seeing the Flanders family playing a bigger role was a nice watch, and I can give credit to the animation being used which just seems really good.
4.5/5, barely rounded down to a 4/5 in the poll.
