I feel I need to write a positive review looking at the list of abuse this has been subjected to!
I can't understand how so many people hated this film. Yeah, it's daft, but come on, how many action films don't have a credibility stretching premise? (Face Off, The Rock, Gone in 60 Seconds, all of the Mission Impossible films etc).
I sat and watched this with my partner last night and we both thoroughly enjoyed it. It pretty much runs in real time, and doesn't let up from start to finish. Jason Statham does exactly what you want (and expect) of him, with his perpetual scowl and well delivered one liners. There was a nice thread of humour throughout, and some fun characters (the dead-pan doctor was a nice touch).
Lighten up people, and get a sense of humour.
