Thought it was fantastic. Jon Bernthal was a perfect choice to play Frank. And I've been a fan of that casting decision since he first appeared in Daredevil. They did a good job of illustrating Frank's mental and emotional health through his hallucinations of his family. I particularly liked one of his last hallucinations when he was confronting Rawlins, where when his family was telling him it was okay, and he could come home with them he was able to sort of let them go, or rather accepting that war was his life now, saying "I am home", and bringing himself back to the fight.the fight scenes were well done, there was an appropriate level of gore and viciousness for Castle's character without overdoing it like that Punisher movie a few years back did. All in all, I was very pleased with it and am very much looking forward to season 2.
