For some reason, I find movies like "how high" and "harold and kumar" just a massive bag of cringe worthy rubbish. I genuinely can't watch them because I genuinely feel embarrassed.
If I'm smoking indica's I like to watch something simple, so I'll watch Family Guy or South Park or maybe something like The Avengers. If I'm smoking a sativa then it's documentaries about space, wildlife documentaries, movies like Pulp Fiction, Layer Cake, Sin City, things with depth and story.
