Okay... it's fairly obvious that if you've seen one of the Road movies, you've seen them all. They're all equally silly but equally enjoyable. If you find one of them stupid, you'll find the rest equally stupid. If you find one of them deep and profound... um... I suppose you'll find the rest equally deep and profound, but please let me know because I think that's highly unlikely. :-) Basically, they're as pointless as Marx brothers movies without QUITE so much zaniness.
