This was the worst movie I've ever seen, no kidding.
From the writing, to the directing, to the music, to the dialogue, to the editing, to the filming, to the character writing, to the stylistic devices, to the screen writing, to the acting.
The sexual moments are incredibly uncomfortable to watch, come out of nowhere, the other scenes are weirdly acted as well, the story telling is absolutely chaotic and not understandable, the plot is horribly weird and makes no sense, the stylistic scenes and flash backs dont fit at all and feel misplaced, the characters are shallow and badly written to the point you think they are all crazy and tripping and there are just so many moments that come out of nowhere and are soooo weird (spoiler, she turns into a giant at the end because she took too many steroids and then they are both giants and run threw northern lights). The whole movie feels like a huge fever dream or a really really really bad trip.
The only good parts about this movie are the jokes about cigarettes and Kristen Stewart's looks.
If you really want to watch it dont do it sober and dont expect ANYTHING good. Make a drinking game out of it.
