I've sort of taken to task of watching all of Kim Sung Oh's work given he's always a great supporting actor and I'm hoping at some point he's a lead. No matter what he is in from a drama to a film he stands out as a great character actor. I found this film to be very good where you have two unlikely people coming together and overcoming their issues. There is a great sense of camaraderie between the firefighters and it's interesting to see their relationships come together. Overall I'd watch this again and the ending does not disappoint.
