Very good.
Some of the best television I have seen since Game of Thrones. It isn't afraid to kill off characters when necessary to telling a good story. That alone gives it a huge advantage--I hate plot armor. Props to the producers.
To the detractors, it's not quite the same as the movies because...um, it doesn't have John Wick in it. No one is going to be the master of death like him, get over it.
