It had some good fight sequences. But besides that, meh. So much made no sense.
People walking around a train with weapons out, blood on them, blood everywhere, and fighting. Yet no one raises an eyebrow about it. A train car with a bar. But no bartender or anyone stationed there. Or no train conductor controlling the train. Just so many things make no sense.
Worth a watch for the fight scenes if you don't expect too much else from it.
