The first half is zany and hilarious. It’s so fast-paced, so much happens, that it might be easy to get lost. But this is to the movie’s benefit, because even the protagonist feels that way sometimes. You’re feeling what he feels. Then about halfway through, the story sharply changes tone, and not in a good way. It becomes an extremely predictable tale of serious seriousness. It feels like they haphazardly slapped together two unrelated scripts: a fun, original comedy about the get-rich-quick schemes of a couple teenagers, and a coming-of-age drama that sprints through every cliché in a race to be as generic as possible.
