Love the series but it seems I must be in the minority in terms of William Zabka - I thought he was stiff as a board starting from his opening lines. It looked like he was just reading them, staring straight forward. He gets better as the series goes on, though, but I thought the first two episodes were cringe-worthy from him in many scenes. Thought Macchio was much better in their scenes.
Would have also preferred if they cut out a lot of the language - was hoping to watch this with the kids but it's got way too much profanity going on which I thought was pretty unnecessary and contributed nothing, and a lot of it seemed forced.
