I guess. I mean it's pretty stupid in parts and there are some throwaway scenes, but overall I found it enjoyable. The focus is really more on style than depth, so as long as you don't go in expecting more than a slick action movie you probably won't be disappointed.
I don't know if you've seen any of Guy Richie's films, but this is pretty much par for course. It's a bit less brutal than some of his other stuff, but similar in tone and style.
