John Wick epitomizes the antihero- he's a ruthless murderer who lives above the law, yet we root for him every step (kick) of the way.
I say I like this series because of its "realism", but that sounds dopey, because I have now seen John dodge about 250,000 bullets, fall unscathed from massive heights, bounced off cars, you get the picture. And, there are no cops in John Wick's world. But, the fight scenes are some of the best I've seen.
I also really like Keanu professionally and what I hear about his personal life.
And JW4 does not disappoint. It is the best of the series. Some new characters and an interesting story line. Plus, enough meat left on the bone for more JW in the future, and possibly a prequel.
Oh, wait, I almost forgot- Keanu has like 3 lines of dialog in this episode!
