I gave it 6 stars because Dong-seok Ma is always fun to watch, otherwise I would have given it 5 stars.
It's not a boring movie, there are some cool fight scenes, but the story is not very exciting and there's just something missing to make it special and interesting.
I also didn't like the cliché "strong" female role they seem to have copied from Hollywood movies. It's so tedious to watch a woman beat up men and act like one of the boys in this try-hard pseudo-cool way.
You can watch it, but don't expect too much.
