It's ultraviolent and there's too much sex, but ultimately it's all used very powerfully to tell an intense but good story. A few great twists and one exceptional episode in particular make it rise above the lesser Marvel Netflix crossovers. I rank it just below Daredevil (Season 1) and just above Luke Cage. If you can stomach the violence, definitely give it a try.
The Punisher (Netflix, 2017) - 4/5
