This is a very different movie. I can see how the filmmakers were indeed trying to be creative in its approach from the perspective of an 'Action Film Star'...
There is some pretty rough dialog throughout that is both intentionally and unintentionally funny in a quirky kind of way. I thought the main guy was pretty cool and played his part well. But, the acting overall is not what you would call the very best, and that's putting it kindly.
I guess the unusual setup and the fight choreography particularly towards the end with the two main Good/Bad guys is what keeps one's interest mostly. But, the script, such as it is, kind of brings the movie down a little.
You have to hand it to the imagination behind some of these films, they do indeed come up with some truly out of left field twists towards the end, which I felt in this case were fairly effective.
I liked the two different fighting styles of the Good/Bad guys at the end. The Bad guy was very much like Bruce Lee, very 'Still' very precise, VERY fast! The Good guy using his Wave technique was more fluid. So, it was rather fascinating watching how their totally different fighting styles worked together.
I would say that overall it is an okay movie, fun in parts, with an unusual premise. To me personally, the ending 'Twists' add another point because of their clever and somewhat vague nature, thus my '6' rating...
Definitely flawed, but if you get into it, it does hold your interest for all these quite disparate reasons.
