What a letdown.
The main problem is that the story is a) just kinda dumb and bad, and b) too condensed.
The protagonist is entirely bland (Good grief, is Raymond Lam ever a charisma black hole!) and none of the relationships get enough space, so any character development is impossible to believe.
All the twists, betrayals etc. are meaningless, because I feel nothing about any of the characters. (except for the princess, because she's hot)
And where the old KFCM worked - the crazy fun fights - just does not work here.
The fights are bland, fake looking and worst of all - boring.
It's just forgettable.
