Nice movie, great acting. Sort of noirish, so to speak.
I'm not sure that a comic thriller is really an apt description. Specially in the second half , comic is not what would spring to mind very often.
But the cast and their performance is excellent and I'd say the storyline is pretty good as well. It doesn't go down the well trodden easy answers - new guy takes all storyline, the surprises along the way keep the suspense alive.
