Coven would have been the best season if they didn't try to cram a 26-episode story into 13 episodes. It was doing SO well, and then the writers woke up, realized they had four or five episodes left, and it fell apart.
You could see the plotlines collapse at the seams one by one.

The way they handled Marie's and Delphine's arcs at the end was criminal.
"Coven" remains the best season title, though, and "Bitchcraft" remains the best season premiere of the series.
