There's not much to say that hasn't been said by others. Midway through I decided I could only understand the plot choices being made if this were supposed to be a horror movie, then the film undermined even that. There is zero character development, none. The main character makes it clear she doesn't fear death, we get glimpses she might care about her gf. But in the end, the only thing she loses is her life, in a quick and relatively painless way. She never has time to regret a single thing she's done. The film tries to paint her as an anti-hero, but her criminality is preying on the elderly, the pain she causes isn't to the greedy or corrupt, but the most vulnerable, so that doesn't work. Some of the rest of the characters have cursory backgrounds established, but not examined. It is just plain bad writing destroying an excellent concept.
