This film has shameless copied, borrowed, stole many other foreign films from Korea, The Man from Nowhere (2010), from Belgium, The Memory of A Killer (2003), and Nicholas Cage's 2014 film, Dying of The Light, as well as a rumor in November, 2014 that Al Pacino and Brian De Palma, director of Scarface (1983) would adapt "The Memory of A Killer" into an American version. This Chinese copycatting film is as close as the Nicholas Cage's role in "Dying of The Light", about a CIA agent with dementia, his body functions were staying mostly fine but his brain got Alzheimer's disease. Then heavily borrowed the story from The Man from Nowhere.
Sammo Hung played the guy who was once the palace guard of the Chinese Communist Party in Beijing, he got such disease and deteriorated rapidly after his retirement. The storyline only added some awkward, unrealistic and highly unlikely romance, and the appendix-like sub-plot of Andy Lau's character, father to a young girl, a hopeless compulsory gambler.
The close combat fighting scenes are also heavily borrowed and copied from most of Steven Seagal's action movies, by breaking knuckles, elbows, knees, ankles, neck of all of his opponents, fighting daggers, long or short knives with bare hands and did the most severe body damages to those who unknowingly fighting an unimaginable fighting machine. But the thing is that Sammo Hung is too fat, too old and too bloated to the extreme, making the fighting scenes just looked more like choreographically awkward rehearsals.
The story, the scenario and the plot were just too contrived and stereotyped in rigid Chinese way. It's neither like "The Man from Nowhere" that connected us to the young girl and the mysterious killing machine guy, nor gave us any empathy connection of how sad the guy in "The Memory of A Killer", trying to not being useless and helpless. The Bodyguard only gave me some awkward and impatient numb feelings, completely disconnected. The awkward senior romance in this film only made me feel pathetic and nauseating.
Hiring those once famous Kung-Fu has-beens as supporting roles were also totally unnecessary, only made the whole film more loose and flat.
This is a pathetic patch-up work with a very poor script.
