I thought it was unintentionally funny. The fight choreographers ran out of ideas often and just rehashed the same few moves again and again. I laughed out loud through much of it and still don’t understand the plot. Easily the worst of the three, but if you like the franchise then it was fine for what it is.
I enjoyed it. Silly mayhem fun in an alternate universe in which everyone is either a hired killer, a retired killer, or a minion of killers.
