Question: Why did Grandpa join the angry mob? It would make much more sense if he was either on his family's side or simply remained completely neutral.
Question: In the scene, where Lenny informs Homer that they're giving away free donuts at the shop and that they're going very fast, why didn't Homer ask Lenny to save him some? If he did and Lenny agreed, Homer wouldn't have to hurry up nor dump silo in the lake, thus the dome situation could have been avoided.
Question: Is there any reason why the EPA couldn't just put the dome over the lake instead of the whole town? I mean, the only thing that actually is causing any pollution is from the lake.
Question: Why is Cargill so determined to keep the people of Springfield trapped in the dome?
Question: Didn't anyone notice Maggie, Lisa, Bart and Marge jump from the treehouse to the sandbox portal without anyone from the very large mob noticing? It seemed like nobody noticed until Homer jumped in and got stuck initially. Everyone in the mob were around the sandbox, how come no one noticed the other four Simpsons jump?
Question: First of all who is the EPA guy and what does he have against Springfield? Secondly, What happens to Spiderpig? Halfway through the movie they just cut him out.
