CS ruined two perfectly good characters. (I liked Hook when he was just a double-crossing sleazy douchebag who wanted to kill Rumple. I could stomach a redemption arc for him, but not the insipid loverboy thing they did. He goes from a 300 year fixation on revenge to a sudden fixation on Emma Swan in the course of a single episode. It was the stupidest shit I’ve ever seen. And it’s just gotten dumber.)
No chemistry and I don’t see that ship doing any good for the show.
