Punisher reviews call the Netflix series (mostly) good, yet overly long

Of all the characters in the Marvel universe, Frank Castle, aka the Punisher, is one of the most morally gray. Neither a hero nor fully a villain. We saw that in Daredevil Season 2, when he squared off against the Devil of Hell’s Kitchen. The Punisher kills, which makes him a bad guy. But he has reasons that make him sympathetic, almost heroic, in his quest to cleanse the world of killers.
