I'm being a little more generous with this movie than it probably deserves, since objectively speaking it really isn't that good. It's pretty stupid, lazily written, lazily shot, lazily directed, and it kind of feels like their making it up as they go along with no real arc. The movie doesn't even really end, it sort of just stops. Having said that, it did make me laugh. It wasn't consistent laughter, but I'd say every 5 minutes or so I got one pretty big laugh. Even when I wasn't laughing, I wasn't exactly bored. Initially I was kind of irritated by Cheech and Chong's antics and there dramatic overuse of the word "man," but pretty quickly they managed to win me over with their charm. Not a great movie, but for a 70s stoner road trip flick, it's about as good as you could expect.
