Even action films need a plot and believable characters. What passes for plot in Extraction is so ludicrously threadbare and lacking in sense that you might as well not have one at all. The central characters are little bundles of cliché tied together with strings of cheesy dialogue. The action itself is, as usual, just mindless violence. The overall experience is like watching someone else play a tedious computer game whose sole object is to shoot anything that moves. The one tiny positive note is a bit of deft camerawork in one scene. And that's it. Really.
