The premise of the movie is a brain-damaged veteran who fights crime, drinks a lot of water, and constantly recites military jargon. The plot moves in predictable paces toward the expected conclusion, eventually focused on an antique spear on display in the National Art Museum, which is the target of the villains who intended to steal it. The chef villain (leader of the gang) is rather likable, manipulative/deceptive, intelligent, and seemed to go out of his way to avoid killing. That is contrasted by the hero who is mentally slow, have a somewhat confusing relationship with a love interest, and he seeks out crime and criminals to fight/punish.

The problem with this movie is the predictability of it. There was never any suspense on what is going to happen. The love interest angle was underdeveloped and uninteresting. The film seemed to start to explore the duality of crime & vigilantism but didn't follow through. The martial arts fight scenes attempted some level of realism, but they are nothing original and became repetitive after awhile. Overall it isn't a bad movie but it fails at creating an original plot after creating a very original hero.
