The chemistry between Luis Mandylor and Scott Adkins is amazing in this. Not sure whos idea it was and how they ended up together on screen, but you can tell they really work with and off each other more than nicely. Having said that, the story itself is nothing special. The title says it all - well you can guess what they do and it won't take a genius to guess how they collect (or try to).
Great fight scenes overall, Scott Adkins has worked with this director a couple of times now, which is always a good thing when it comes to working smoothly. What may be a bit surprising (at least was for me), that Luis Mandylor looks quite good when he actually gets to fight! Scott Adkins you expect him to be great and he is, but Luis? Which may be a testament to the director, fight choreographer and the stunt man of course, but also to his willingness to learn a bit (and maybe he did have some prior boxing knowledge that I was just not aware of).
Combine all that and you get a more than decent and very amusing/entertaining movie. You have to like this stuff of course (blood and some nudity included)! If not than you won't like it, simple as that.
