Your favorite "cop/assassin comes out of retirement" movie?

Hey guys. So I just saw November Man on Netflix and with watching John Wick last year. I love movies where a guy comes back and all hell breaks loose. Taken in a sense is one and I loved the first and 3rd one. Red was also a great one, though the sequel was fun. I didn't enjoy it as much. I was wondering if you guys have some great ones I can watch.
