I don't recall seeing a movie like this in a good, long time. It's a macho-action-thriller that didn't have an A-list budget, but probably didn't really need it, either. You used to see more of this back in the 70s and 80s; these days this kind of movie usually has a much bigger budget, with the requisite special effects and massive action sequences such a budget buys. Here, though, it's a little different.
Good action, intriguing setup (definitely no good-guy/bad-guy here; nobody is completely innocent by any stretch), and pretty good characters. And a story that's somewhat better than you usually find in this particular kind of film.
Don't know that Jason Statham's a great actor, exactly, but he's definitely a presence and he's got others to do the acting around him, and he performs in a several action scenes that come right up to the edge without getting silly. And I liked the basic plausibility in most of the scenes.
I'm a guy, and Killer Elite is a pretty decent "guy" movie. You could do worse.
