Saw Kate and The Protege.
Both have elements of that John Wick "killer on a revenge spree", but The Protege is definitely the better one of the two.
Helped by the presence of Maggie Q, Michael Keaton, and Sam L Jackson. Doesn't have quite the same raw flow of action sequences, but develops nicely with some good character banter.
Kate is much more action-throttle, but doesn't have quite the dialogue to sell it. That and the "twist" is pretty obvious from the "I want to retire" statement in the first 10 minutes.
