No, just a small assassination group and the Yakuza. So in that way it is not like John Wick or Gunpowder Milkshake, there is no Library or Hotel or similar place. Kate is simply a badass assassin. So a little more like Chev Chelios (Crank) in that regard, although Chev was not an assassin. John Wick is jus the first badass assassin I could think of. Perhaps Kate is more an older Mindy Macready (Kick-Ass). There is no shady government program, ala Hanna, or super drug, ala Lucy. She is not trying to recover her child, ala Furie.
I watch a lot of action movies
So with more thought my review will be:
D.O.A meets
John Wick older Mindy Macready or Cataleya (Colombiana), not as insane as Crank, which had a similar premise. This movie is completely predictable. It did not matter, it was a blast of an action movie. There have been a few female lead action films in recent years and this is one of the better ones.
The poster is very Gunpowder Milkshake in style.
