I enjoyed this despite it being very frustrating at times. The basic premise is good and the main storyline is also very good. However, it is let down by too many plot holes and some of the acting is very amateurish. Nevertheless if you approach this in the same way as you would something like Die Hard or anything with the likes of Jason Statham or Jean Claude Van Damme then you will get enjoyment from it.
Like most action movies the action sequences in this become ever more preposterous to the point where I started wondering whether it was a parody. Entertaining but in a trashy way. You know the drill, the enemies have all the firepower of a small army but can't hit anything remotely close to a target while the protagonists can bring down said army with a small handgun and only two bullets.
