If this was a book it would be absolutely brilliant, the story by itself is very emotional. But the movie is just frustrating, boring in places and highly unrealistic. They also didn't really know which direction they wanted to take it in so it ended up being a mishmash of comedy, high school romance and deep psychological drama which in most places didn't work together. Decent performances from the actors but nothing special. Overall poor writing and direction not at the same level of an incredibly emotional concept with a great view (albeit slightly stereotypical) of mental illness and grief.
