“Cold Blood” (*** out of four) was a moody melodrama about a lifelong hitman (Jean Reno) who lives in isolation at a cabin on the edge of a lake. When an injured woman (Sarah Lind) arrives at his house out of nowhere, he decides to risk everything to save her; meanwhile a hard-nosed cop (Joe Anderson) is trying to find her and solve the case. Reno is masterful and appears to be more-or-less playing Leon again from “The Professional” and Anderson seems to be playing a similar character he played in “Backdraft 2” and their strong performances and characterizations help carry this imperfect film through its lulls. Thierry Arbogast’s spectacular cinematography is a definite plus as well.
