Greatest comedy of all time, period.
Chromium_55 March 2005
I never planned to write a review for this movie, until I took a stroll through the user comments, and was shocked at all the people who think it is.... God help us... overrated. No way. If anything, it is UNDERrated. I see people complaining about the endless shouting, the over the top slapstick, the brashness, the loudness, the length. I can only conclude that these people are a bunch of humorless dorks.

First of all, you can't just sit down to watch a three hour movie without knowing what you're in for. This is not your typical comedy--this is an EPIC comedy, the first of its kind, that inspired other such epics as "Those Magnificent Men in their Flying Machines" and "The Great Race" (which happens to be my favorite comedy--in fact, I'd like to say it's the better movie, but props go to this one for inventing the genre). And I can't speak for everyone else, but this movie leaves me laughing from start to finish.

Yes, it is very long, but it NEVER has a dull moment. Even if the amazing car stunts aren't particularly funny, you can't tell me they aren't wildly entertaining. I have yet to see an action movie with better car chases than these. And yes, the slapstick is ridiculously over the top, although I can't see how that's a problem (the gas station scene is one of the funniest in movie history, in my opinion). But underneath all the slapstick and shouting, holding the whole movie together, is that incredibly cynical message. It is a movie about kind, decent folks turning into law-breaking lunatics and ruining their lives for the sake of money. The subplot with Spencer Tracey realizing his entire life has been a waste, and then ruining what life he has left, is one of the most tragic story lines I have seen. But it's also pretty darn funny.

All the critics need to lighten up and see this for the absurd, delirious, hysterical farce it is.

10/10 stars
