The good news: the movie kept me awake and Michael Fassbender and Dominic West are strong leads as the titular centurion and the general of the ninth legion, respectively. The bad news: the movie is a slightly cheesy period B actioner, rife with bloody, gory slo-mo fighting with squibs of gushing red blood and lopping off of heads. Think Monty Python and the Holy Grail. Only straight.
The men are far stronger than the ancillary action babes in fur and anachronistic hair and make-up. Think Raquel Welch in One Million Years B.C. Fassbender's girl-interest sub-plot is plain silly.
Both West and Fassbender had auditioned for Doomsday, and Marshall wanted to work with them on this Pathe/Warner Bros. funded production.
