Why Didn't I Like The Fantastic Mr. Fox?

Note that the title is not why I didn't like the film.

Isabel and I got around to watching the stop-motion film last night...or, rather, I got around to watching it. The movie put Isabel to sleep no less than three times.
(I'm not sure if it's a bigger deal whether a movie puts her to sleep once for most of the film or three times spread throughout.)
Anyway, the movie should have worked for me. I like animation. I'm a sucker for old-timey stop motion.
I've enjoyed a lot of Wes Anderson's films.
I'm a Roald Dahl fan (although I've never read this book...which might suggest that a lack of nostalgia prevented me from embracing the narrative).
I even like animals...especially of the talking sort.

So why didn't this movie work for me?

I'm not sure.

Maybe I wasn't in the mood for slow-burn, nervous humor after a day of grading.
Maybe I was put off by the fact that the goodness and identifiability of the animals contrasted with the utterly grotesque, morally bankrupt, and alienating humans.

Do all three poultry farmers have to be evil? Couldn't there have been a nice poultry farmer somewhere?

Are the farmers problematic because they are farmers, or are we supposed to get the sense that these are particularly bad farmers because they appear to hoard their chickens for themselves?

Whatever the original story's intent, I kept feeling like the movie was going to slip into some kind of perverse environmentalist propaganda. I don't think it ever quite did...but I wasn't sure. The plot was very episodic, so themes seemed to shift from one bit to the next.

I did like that Mr. Fox's subversive lifestyle came with its costs. His major heist schemes are for the thrill of law-breaking, rather than out of survival or necessity...and he does penance as a result of his sins. Nevertheless, if the movie suggests he is clearly wrong for stealing from corporate farmers, the movie ends with an ambiguous sense that he is somehow more justified stealing from the Big Box Walmart analog at the end of the movie (although the fact that it bears the names of the three evil farmers might suggest that the story will repeat its cycle). Mr. Fox isn't an ideal protagonist, and the film is aware of that, so I think that's in its favor.

For the most part, the movie just seemed to be animals having awkward conversations and then apologizing later for being awkward.

What did I miss?
