I have to start out by talking about how bad this movie is and then we can get into the cult classic-y aspects. This movie is complete shit. The narrative, when it exists, is overly complicated and dizzying. The entire film is a disparaging, nihilistic and all around depressing alien abduction experience.
Now for the good aspects. The entire film is a disparaging, nihilistic and all around depressing alien abduction experience. I mean seriously, I’m fucking depressed right now after watching this (and in general because I’m not living up to my own expectations). There’s tons of awesome body horror and an overall scary, grimy look to the entire movie.
Boom, those are your basic ingredients for a cult classic. You just make an incredibly shitty movie, make sure it’s not easy to understand then craft everything to look cool as shit.
