Good to see the Undisputed movies on a list like this. I just recently learnt there's a fourth one all about Boyka again, and I can't wait to see it.
John Wick 2 needs to be there, though. That might legit be the best Western action movie ever made. So many long, beautifully-framed shots of gorgeous action, zero shaky cam or confusing cuts. It's a whole different league from the first movie, and the first movie was incredible.
Kill Bill is a bizarre choice for number 2. Uma Thurman is so slow and unconvincing in all the shots they didn't use her stunt double for. And some of those modern Chinese wuxia movies like Man of Tai Chi become totally incomprehensible as soon as the action begins. Everything is done on wires and the editing and cuts to different angles just makes them look like garbage.
