TOMBOY is posited as some kind of gender-swap action thriller but in reality it's merely an indie drama with great expectations which are dashed early on. Michelle Rodriguez plays an assassin, starting out as a guy, only to wake up to find that she's become a woman thanks to some unorthodox gender reassignment work. The problem is that the male Rodriguez looks like nothing more than the actress with a glued-on beard and some dodgy CGI work. This aspect of the movie feels like little more than a gimmick and Rodriguez's gruff voice is pretty pathetic too. The rest of the film is the usual low rent mix of bad guys and cheap-looking action scenes which invariably disappoint. Pity poor old Sigourney Weaver, stuck in one of those roles where she's constantly talking in a room and looking very bored.
