Watched this last night. Good movie. It is/was being billed as being from the minds that brough us "Snatch" and "Lock Stock and 2 Smoking Barrels"...but that isn't entirely accurate. The Producer of those two films (two of my favorites) tried his hand at directing this time (instead of having Guy Ritchie at the helm). It is also billed as being "Hilarious". Not accurate either.
That said, it is still a good English gangster movie. The director (Mathew Vaughn) doesn't have Guy Ritchie's great camera movements and editing skills and the movie lacks Ritchie's genuinely hilarious screenwriting...but it is tough and gritty and has a bunch of good twists. Good performances all around too.
Don't go in expecting "Lock Stock III" (like I did) but it is definitely worth a watch.
