This is a charming project in theory, but as the film goes along it becomes harder and harder to like the protagonist. Sure, his dad died, but he's a total jerk to everyone around him without any provocation whatsoever. He should show much more character development much earlier in the movie.
Frankly, i understand the type of stress he's going through, but i don't like the stereotype of a mentally ill person behaving chaotically while everyone around them is trying their best to be nice. This is a hollywood stereotype that basically never happens in real life, and the reality is that people don't keep acting like this unless others are bullying/abusing them, and that's really not happening.
The film in general would be much better if there were real pressing reasons for him to act these ways, because i don't think leaning on/fetishizing teen angst is a good way for the script to fill itself out.
The climax of the film is just a bunch of arguments and bad behavior when it should have been nice, and by the time we get to the uplifting segments. It's too little too late, because the protagonist still has not experienced any character development. The only thing that's changed is his haircut and the people around him, and it's utterly implausible that these pretty girls would be talking to him. This isn't because he's overweight, in fact i think his appearance is generally fine, but his personality in this film is just utter trash.
