I didn't know about this film until I found that it was dubbed in Hindi. I saw it and found it to be unexpectedly good as most South Korean action thrillers are. COMMITMENT doesn't add anything new to the genre but provides a pretty great deal of action packed entertainment with a good portrayal of human emotions and relations, though the emotions slightly falter towards the end.
Choi Seung-hyun is good in his role. This is his first film I've seen. Other actors too were good. The screenplay is decent, and there are a lot of impressive moments throughout the film. The action scenes and visuals are amazing, as is the cinematography. Editing is fine.
Besides, COMMITMENT also has a great portrayal of emotions throughout. The story being realistic helps to connect to the characters and feel their pain. The heartwarming brother-sister relation is brought out very well. Full marks to the director for utilising and extracting great performances from his actors.
However, the film falters in the end. The climax was a good one but the emotions didn't come out well. It's only here that it's hard to feel for the characters, otherwise there's not a single scene where you won't.
But that being a minor flaw doesn't affect the film's entertainment quotient, and due to that I recommend watching COMMITMENT.
