It's very, very weak. Only the first 10 minutes or so are ok.
I wished for Jason Statham being a badass for 90 minutes. What I got was some flashbacks and uninteresting characters doing a piss poor robbery with casualties that we were introduced to (for no reason). Statham shooting about three guys at the end in a very straightforward matter. His own crew nowhere to be seen.
Stick to the trailer and you'll have more fun remembering this movie.
