It's okay, very much a stoner movie and would probably be hilarious under the right circumstances. If you like the show you will likely enjoy this, I do and did.
As you might expect the story doesn't make much sense but that doesn't matter much. All the characters are there plus some new ones (I think). My personal favourite being Carl, the sarcastic neighbour.
I remember watching this religiously over last summer on Adult Swim. Worth a sweep methinks.
On an (totally unrelated) aside, has anybody started using Azureus Vuze yet? I'm not too sure what the difference is from old Blue Frog (bar the obvious video gubbins)...
Im using it, the advanced tab brings up the same as normal azureus, The fancy bit is useful for browsing and going 'ooh, thats nice I'll sweep that' as far as I can tell, I don't notice any difference in speeds/reliability, the uPnP seems to be a bit better at sorting out port forwarding/nat problems by itself though, which is nice.
