Guess it makes sense then where they spent all their effort in creating an effective movie from what I read. Probably one of those movies where if you lessen your expectations by a lot, having a weird taste, and watched it more than once, then it might someday be decent. It's like making a movie with a scene at a camp or fighting ground and its only highlights are that the cg rocks, grass, and dirt laying around in the landscape look so realistic.
The choreography and the fancy moves might be appealing. The knife slashes were honesty not bad and looked brutal but if you watch the actor on screen keenly, you'll notice what's weird.
Its not just clear that he didn't perform the stunts himself but the actor also looks very stiff and his moves don't look flexible and fluid at all. He's built like a tank and that's not helping at all. He should've lost muscle mass and focussed on looking nimble.
