The Dark Knight

I finally saw "The Dark Knight" this past weekend. I do agree that it is a great action movie, with much better acting and far more drama than the typical summer blockbusters that they throw at us now and am even willing to go on record and say that it is one of the best action movies ever made, along with The Matrix, Die Hard, Terminator 2 and the like. However, I can't possibly annoint this film the best of all time, as it is listed as on IMDB. I, in fact, almost consider it an outrage taht this film could be rated higher than Shawshank, The Godfather, Casablanca, and some of the absoulte all time greats. I don't understand how that could have happened. I give it a solid 8.5/10, which is the highest rating I've given to a film this year, but c'mon, best ever? The only thing about the film which approaches greatness is Heath Ledger's performance.
