It's a generic revenge action movie story line, with slightly above average dialogue and the usual modern-day mish-mash of fighting styles (brawler, samurai, capoeira, etc.). The goodness mostly came from the direction, art, and visual devices employed. Lots of papercut and CGI that looked like papercut comprising the cutscenes and folded into the storyline.
(Hah, see what I did there? folded? HAH! I kill me.)
I do love me a good action movie now and then as a guilty pleasure but they rarely stick with me as they're just fleeting pleasures.
This one though, I may come back to...
(Also served to remind me how painfully out of shape I am. I think I'm going to tackle that in a serious manner.)
