This is not your typical Hollywood production, but wow was it produced really well.
The score was perfect. The setting outstanding. The cinematography on point. The acting by all cast - even extras (mostly ex-convicts) was very convincing and intense, and Joe Cole nailed his role. The directing was fairly decent although the last fight scene was just too many close ups.
My main beef is the writing - either bad editing or cutting by the director. There were too many scenes that were missing info, such as what did the letters from his dad say? Why even have that in the film if it wont be elaborated. My other beef is the lack of subtitles where subtitles were needed (90% of the film). I'm not sure if it was my copy missing all the important dialogue subtitled, or the actual film, but I was left unsatisfied not knowing what everyone was saying, or at least many important scenes.
Nevertheless, a really intense film based on a true story, filmed really well overall. A great watch, especially if you're into the martial arts and Muay Thai. A well deserved 8/10 from me.
