Stupid & Stupider
If Harry and Lloyd from "Dumb and Dumber" had starred in "The Hangover" the outcome would probably have been a bit like "Dude, Where's My Car?" but funnier. Now if that appeals then maybe you will enjoy "Dude, Where's My Car?" because we have two stoner friends retracing their steps from the night before and getting into a series of comic situations from a run in with some angry Jocks to arriving at a strip joint to find that everyone knows them. The trouble is that whilst that isn't a bad idea it is so ridiculously safe when it comes to the humour that not only does so much of it fail but a lot of it feels like it has been pinched from other movies.
After a heavy night best friends Jesse (Ashton Kutcher - Down to You) and Chester (Seann William Scott - Road Trip) have total memory loss over the night before. Realising that they are due at their girlfriends for their anniversary they discover their car is missing with the gifts in. So slowly they try to piece together what they did the night before leading to a series of misadventures whilst trying to make it up to their girlfriends.
So as I pointed out "Dude, Where's My Car?" is like an earlier version of "The Hangover" but with a couple of characters who are even dumber than Harry and Lloyd. The trouble with the movie is not the idea but the outcome as the jokes are not only extremely juvenile but far too safe. So instead of delivering some risky sex comedy or something close to brutal comic violence we get the safe such as a group of people who think they are aliens and a scene pinched from "Ace Ventura" involving a transgender lap dancer. So few of the jokes are actually amusing but the ones which do work such as the tattoo scene are iconic.
But the level of humour in "Dude, Where's My Car?" is not the only problem as sadly Ashton Kutcher and Seann William Scott end up annoying. The whole stoned and stoner routine is so weak that it is impossible to like them as characters or find half of the stupid things they do amusing.
What this all boils down to is that "Dude, Where's My Car?" ends up like someone saw in to the future and tried to combine "Dumb and Dumber" with "The Hangover" but didn't succeed in figuring out how to make it funny.
