Frank makes me laugh
Maybe it's gallows humor, but something about Bernthal's Punisher plays like a well-timed punchline with me at times.
First time was when the Irish gang members set off his trap.
And in the season 2 finale, I laughed out loud when Billy called out to Curtis, and Frank walks in. Also when Frank cuts off Billy's apology. Huge LOL when Schulz screams at him, calling him a murderer, and his only response is, "yeah."
It's really the only aspect of this series that reminds me of its comic book origins. And the biggest part of why Bernthal beats out Stevenson, Jane and Lundgren as my favorite Punisher.
