One thing I learned from this movie
A jacket can be a scary weapon when used against a trained hitman wielding two knives.
WHAT?
I could see it if this was a Jackie Chan movie - he can make pretty much anything into an entertaining and effective weapon, but just a dude threatens and beats up a trained hitman+knives-combo WITH HIS JACKET - it's a bit far fetched.
Everything else about this movie is very realistic, though.
(just kidding)
