SilentDawn’s review published on Letterboxd:
Part Two of Preparing (As Much As Humanly Possible) For Inherent Vice
The definitive stoner film and one of those comedies that still work regardless of some dated elements; Up in Smoke is a goofy, silly, and downright weird piece of work that is gleefully deranged as it is interestingly sweet. The rambling nature of it all suggests something deeper and more longing, but it never quite goes there. It's Cheech and Chong, what did you expect?
"HEY! MELLOW OUT MAN!"
