Lack of good storyline.

It's fun, it's light, [but] it has a hard time when its tries to get heavy.

n my opinion it was a great movie with some interesting elements, even though having some plot holes and the ending probably was just too messy and crammed together, but still fun to watch and not your casual movie that is similar to all other ones.

Exactly the movie you think it is, but not the movie you want it to be.
