A strange cinematic bisque, Overlord so effectively stirs genuinely jarring horror elements into a gripping war movie until it's impossible to distinguish the ingredients in the pot.  It somehow combines tropes that have survived throughout decades of movies and books and video games into something new and...can you use the word "refreshing" about a movie that features so many Nazi entrails?  To hell with it--I'm using it, anyway.  Overlord is ballsy, well-made, and--if you're not terribly squeamish--a damn good time.
