This episode managed to be a bit better than I expected. With the lack of a couch gag, a single plot and actually some solid writing... yeah this was a Selman episode alright.
The first act is probably the weakest part of the episode, which is actually a rare thing for me to say about modern Simpson episodes as most of the time this little side-act manages to pull off some decent jokes before moving to the main plot. It also felt like it didn't really lead into the main plot, so this was basically a sub-plot that only lasted in 1 act. Nonetheless, there were still some good jokes to be found. I like how Homer and Bart teamed up in this grounded act, and how finding good eggs is pretty relatable to me IRL. It did feel like Ned behaved differently than I imagined, he usually doesn't deny Homer when he ''borrows'' his stuff, yet with some eggs he's suddenly a lot more protective. I don't really buy that stealing food makes it more delicious, but I liked the joke with Homer wanting Flanders to go after him after giving up.
Then for the main plot, its time for Marge and Lisa to take over Homer and Bart's spotlight. The new scientists were pretty good characters, I'm not familiar with the people voicing them but they did bring some good lines. Marge's concern for Lisa is understandable and done quite well, though it seems unusual for her to buy into Homer's advice while he thinks that he knows what woman think. In some way his plan could've worked, but not in this case. Most of the scenes in the airbase were pretty fun, kinda hoped we would've seen more of the other Springfieldians. They did show a funny add atleast.
The episode got at its best with the family joining in, I especially liked the rivalry between Marge and Lisa. The scene with Homer and Lisa thinking the same subject to different directions was probably the funniest part of the episode. I like how much Marge shined in her training, and eventually going as far as wanting to go to Mars with Lisa. Loved that joke where Homer and Bart pretended to listen. The ending with the rocket not launching didn't really suprise me, but maybe they could've executed that part better. And I liked the future ending where the nod-bot took Bart's place, good continuation of a previous good joke.
So overall, its a very solid episode and a good way to end this streak of mediocre episodes from the previous airings. One of the best of its season, in the top 3 alongside Halloween of Horror and Barthood.
4.5/5, rounded to a 5/5 in the poll.
