This is a fast paced action thriller with an anticipated twist, that is fairly well acted by Adkins, James Cosmo (of Braveheart fame) and WWE's Wade Barret.
Like stylish action thrillers since Bourne, it sees the protagonist as a fallen American hero in London. In Keeping with the zeitgeist, our hero and villain are tech savy and expertly trained in hand to hand combat. There is of course homage to the genre in the form of high speed antics in a classic German 'whip' (in this case a beautiful example of a 1984 BMW 635 csi). Night action around famed London landmarks adds to the element.
There is some empathy inducing, partial blurring of the good/bad divide through the character of the grandfather, but not the sort of moral dilemma that will hold attention after the credits role.
Certainly watchable, if more so for the visuals than the dialogue, and fairly engaging. The action choreography was quite decent and, as someone who has been on that side of production, lending a sense of 'believable' to the fight sequences.
Better than a Sunday afternoon 'fighty film'.
