I don't think this deserves 5 stars. It really isn't that bad.

The cinematography and characters were nice. I liked them. I enjoyed the plot, and even though some things were predictable, it wasn't as bad as some other shows. The fight scenes were also well-made. Yes, there isn't huge character development, but this is not surprising for a movie.

Some parts of the movie didn't make much sense, which is one negative aspect of the movie. Some things could have been explained better or delved into more. Though it isn't that big of a problem. I would like a second movie, but I don't think it will happen.
Aside from that, I recommend this movie. It's a great watch.
