I really enjoy the movie, still. It has some great animation and vocal performances. I love the moments of Bart trying to bond with Flanders. There are a lot of jokes that I still remember well, like the innocent family that looks like Bart's markup of the wanted poster, Homer's face pasted onto Michael Jordan's body in his wallet, the Disney animal undressing, Marge yelling "SOMEBODY THROW THE GODDAMN BOMB!"... I actually might have to rewatch today. The commentaries are great too.
My only real disappointment with the film is that the Itchy and Scratchy short at the beginning of the film feels incredibly tame violence and gore-wise compared to what they show on almost any episode of the show on TV. There's a shot of internal organs flying around from and explosion, but there's no blood or any of the crazy, almost Happy Tree Friend's level of ridiculousness that Scratchy typically endures. He gets stabbed a few times, his eyeball is expanded from decompression in space, then he gets filled with misses and the explosion takes place off screen for the most part.
