This movie was rather enjoyable. Sure, it wasn't a revolutionary movie in the Hong Kong cinema, but it was actually quite entertaining.
Writers Wai Lun Ng and Dante Lam managed to put together a storyline and script that proved entertaining from start to end. Sure, the movie was crammed with cliché characters, but it actually worked out well enough, given the concept of the story.
"San Cheung Sau" (aka "The Sniper") is an action- and adrenaline-driven crime thriller with an adequately written storyline that was predictable and generic at times, but was helped along nicely by the action. It should be said that while director Dante Lam is good at taking the audience from A to B throughout the movie, then there isn't room for surprises and twists to the storyline, so it was a somewhat predictable storyline.
The cast ensemble for the movie was good and there are some familiar faces on the cast list, if you are familiar with Hong Kong cinema. Edison Chen (playing OJ) and Richie Jen (playing Hartman) are in the leading roles, but the movie was actually carried mostly by Xiaoming Huang (playing Lincoln).
There is a good amount of action and shooting in the movie, and that is definitely something that gives the movie an injection and keeps it from falling into a slump.
My rating of "San Cheung Sau" lands on a six out of ten stars.
