Could have been good, but lazy

I like Adkins, in a Van Damme kind of way, but let's be honest, he's even less able to carry a movie on his acting chops alone.

The whole movie feels cheap. Sometimes in a clever way, as in the constrained settings, but mostly in a, well, cheap way.

Adkins is pushing 50 now, and it feels as though he's not trying that much anymore. Eve used to be a smoke show, but that was 20 years ago; she's still apparently to expensive to actually appear in more than one scene, though.

Photography is competent if uninspired, music is absent, it could be an OK movie, but the script needs so much tightening!

Characters feel flat, artificial, cookie-cutter, and the actors feel jaded. Except for the actress playing Mona, she gives it an honest try.

The dialog-to-brawling ratio is very unfavourable for Adkins, who also looks fairly awkward handling firearms. The script has more holes than plot, but could have been rather easily fixed, which is all the more frustrating.
Giving Adkins the John Wick training is probably expensive; proof-reading a 50 pages script is probably affordable.

Oh well, Adkins has done worst in the past.
But not often.
