I'm not sure what this movie is trying to do.
Who are you meant to root for here? There are many films with flawed protagonists or anti heroes, but this isn't that. It's just a movie about some woman who spends most of the movie basically asking for a beating and vaping the entire movie.
The first few minutes made me think that the main character was supposed to be good person who does work that people don't appreciate, like a process server or a teacher in Florida... But no. Shes genuinely a terrible person. As the movie goes on, I just started disliking her more and more.
I really only kept watching to see her get her comeuppance... But she doesn't . Not until the very end anyway, and by then it just doesn't feel like it was enough.
I think another review put it best with "First you hate the main character, then you hate all the characters, and by the end you just hate the movie entirely."
