“Marauders” (*** out of four) was a gripping underworld thriller about a violent bank heist that appears to have been orchestrated by its cold-blooded owner (Bruce Willis). Upon further investigation from the F.B.I., a larger conspiracy appears to be at work. Intricate and intelligent screenplay takes plenty of twists and turns and is hard to follow at times but is worth sticking through. Willis is good in an unusual villain role but Christopher Meloni dominates the film and commands every scene as the lead F.B.I. agent on the case.
