The reason Bad Trip waffles so drastically between painful and thrilling is that it basically combines execrable Improv Everywhere-style stunts, in which performers assault people just trying to live their lives with hokey shtick, and Borat -style stunts, in which the performer is a wild card clown making a surreal spectacle of themselves in front of those same normal people — often playing on their prejudices and expectations of what that clown is meant to represent in the process (Borat was using people’s assumptions about the “backward former Eastern Bloc” to explore their own cultural blindspots and stock prejudices).
There's also nothing that's so outlandish that you'll find yourself talking about it afterwards, such as the astonishing Rudy Giuliani interview in the much-superior Borat Subsequent Moviefilm .
