How sad is this?

Fun premise, good actors, bad writing. This film seemed to have potential at the beginning but it quickly devolves into a trite action film. Ultimately it's very boring.

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.

This is a coming of age storyline that you've seen in one form or another for decades. It takes a truly unique voice to make yet another one worth watching.
