Perfectly done stunts etc and all actors knew their lines without one slip-up.
What I didn't like
Some of the dialogue could have been better. Example:
A: “She just knocked out her girlfriend with a vase.”
B: “Nobody’s perfect.”
My overall impression
Even though this kind of humor isn’t usually funny to me, by the time the curtain went down I sat there admiring the cleverness and bleakness of the whole project. But some of the barfing was laugh-out-loud funny. However, all the violence gave me nightmares!
