I confess i didn't really laugh that much, but i did smile often. I didn't feel any of the jokes really fell flat, just they weren't lol quality.
I felt this was one of the best scenes in the film, along with the epiphany scene. Also, did you not happen to notice that Marge was leaving Homer? I figured it was pretty obvious. I mean, sure it's happened plenty of times in the series, but it was much more dramatic (outside of season 1) here than before.The movie actually takes a incredibly weird turn for a second where She leaves a video for Homer telling him she's left to go back to Springfield. It sounds incredibly serious and it's just a weird moment.
Overall, i consider it a decent film. It doesn't really deserve any awards, but it is pretty rad seeing it all on a big screen. The plot, although not that great, could only appear in a movie and could of been far, far worse. If you been watching the recent series, you will enjoy this movie far more though, as you'll be more familiar with the style presented here.
Is it also worth pointing out that Maggie seems to have finally said her first word in front of the rest of the family?
