The ending was horrible, I can somewhat emphasize and visualize the situation but the way it developed and ended was lackluster and disappointing as hell. I don’t really know if this is NTr or not but it sure felt like it (that scene was so hard to read and unpleasant), the character development was lacking and really rushed, the build up to the ending could have been much more detailed and fleshed out. There wasn’t really any time to digest what happened (some parts just felt forced and unrealistic).
If the goal was to make the audience as uncomfortable and annoyed as posible then it’s a success.
