I just finished Season 2 of Daredevil and it was so good! I love 'The Punisher'! In my opinion he stole the season and his and Karen's dynamic was so interesting to watch.
Frank Castle is haunted and hunted after the murder of his family and becomes a vigilante known in the criminal underworld as "the Punisher", who aims to fight crime by any means necessary.
the best part of the season to me was definitely the punisher and i love the idea of karen and him together. Hopefully we'll see more of frank in the next season!
