The Simpsons Movie

Plot from Flixster:
When Homer mistakenly pollutes the river with toxic waste from his "Pig Crap" silo, he causes the EPA to encase Springfield in a glass dome, and must save them before President Schwarzenegger gives the order for the town to be destroyed.

My take:
Full of in-jokes that made it enjoyable, but basically just a longer Simpsons episode with some 3D effects. As Homer put it, why are we paying to watch something we can watch on TV?
