Have the other reviewers been threatened with bodily harm?

Rating: 3/10 (14 February 2017)

... that's the only reason I can think of for 8.5 stars.
Sure, nicely choreographed fight scenes. That's about all you can say for this. Almost no plot. The movie doesn't get me to care about any of the characters, not even the main character. I found it difficult to believe that the opponents of the main character could be so incredibly stupid as to make the same tactical mistakes over and over again. This was a big disappointment; I almost walked out of the theater. I give it a solid three stars because I didn't.
If you're 15 and male, and like nonstop violence, yes, you'll enjoy this. Otherwise, I'd spend money on something else.
