This could have been a great movie - a descent into darkness/madness in the back streets and dimly lit alleyways of Bangkok. However, the movie tries too hard and is far too bloody and stylized and ultimately fails. While Ryan Gosling performance as a Thai boxer out avenge his brother's death is dark and brooding (and sometimes downright depressing) and while he and the Thai actor playing the deranged police detective carry most of the film, Kristin Scott Thomas's over the top, foul mouthed, chain smoking mother and head of some unnamed mafia group not only drags down the movie but at times makes it barely watchable. And not sure why there is an attempt to draw some sort of sympathy for Gosling's onscreen brother as a mentally deranged sex offender. Thankfully he is offed early but why watch a film about revenge for a character that is completely unlikeable? Style over substance and too much violence sink this film.
