Sorry to bring a thread back from the dead, but...well...we don't get out much.
We saw this last week, and we both liked it. Sure, it was basically a ninety minute version of a half-hour TV show. That's pretty much what we were expecting, and that's what we got.
Anything else wouldn't have been the Simpsons. I guess some people were expecting them to experiment, push the envelope, branch out somehow...? But come on. The show has been running fifteen years (more? I should look this up) and clearly the formula works. We just got season 10 on DVD for Pedro's birthday and it's the first season we didn't see when it was running or in syndication. We've seen every episode of seasons 1 - 9 (most of them more than twice) and season 10 still makes us laugh. What more can you ask from a motherfuck*ng cartoon?
This isn't directed at anyone here, per se, but more at the general rumblings of "sure it was funny, but it still sucked" that I have heard since this movie opened. Just needed to get it off my chest.
