The Simpsons Movie Voted One Of The Best Movies Of All Time?

I, like most of America, saw The Simpsons Movie last weekend. An enjoyable film, with a lot of laughs, but still may-be 10 years too late. Most of the people I spoke with agreed that it was good but not great. My major complaint was that I wanted to see more of the film set in Springfield. I wanted to see more of the signature characters that we've all fallen in love with over the last 18 years.So I was shocked to find that the movie was voted as one of the best films of all time. Already?

Okay, to be fair, most new films with a built in fanboy audience immediately show up on the reader-voted Internet Movie Database top 250 movies of all time list. But as more people see the film, and more votes are counted, the film usually falls off the list completely (or at least into the 200's). The Simpsons Movie made it's debut on the list at around #33, which is a huge feat. The movie has since fallen to an 8.3 rating to be ranked as the #139th best movie of all time. That's a couple points higher than such classics as Die Hard, The Princess Bride, The Graduate, Butch Cassidy and the Sundance Kid, Federico Fellini's 8 1/2, Dog Day Afternoon, Trainspotting, Groundhogs Day, Toy Story and Stand By Me.  Also it must be noted that only votes from regular imdb voters are considered in the top 250, so first time fanboy voters trying to spike the rating aren't put into consideration.

With 36,600 user votes, Simpsons seems to be holding its spot on the list.  So the question is: Is The Simpsons Movie one of the best movies of all time? Does it deserve this placement?
