The action and fighting were all great but the use of slow motion replays on intense moments didn't work. Story and acting were weak but Tony Jaa single handedly made the movie crazy entertaining. It was as much a parkour/ gymnastics movie as it was a martial arts movie. Took a while to get the action moving.
If I gave movies 3 stars, this would surely be it. Tony Jaa is one the most talented martial artist stars to come around in a long time. He contains the power of Bruce Lee as well as the sheer athleticism of Jackie Chan. But unfortunately, he's extremely dull as far as character goes and doesn't particularly give the audience any reason to root for him.
The movie plays like a prank on Jaa that Jaa isn't in on. He's all bland seriousness while the movie is putting him through greater and greater absurdities with Simpsons-like comic escalation. Unfortunately, Jaa dominates a little too handily. In some of the fight scenes his opponents are just standing around waiting to get punched in the face. But, hey, it's all in good fun.
