It's not directed by the same person every episode. Skyler's character development made her antagonistic simply because she was getting in the way of Walt doing what he feel he needs. Personally, I feel like the farther she descends into the ugly world that Walt has made for himself, the more engaging she is and the more likable she is in terms of the universe of the show.
Some people will simply dislike the quieter episodes because that's not what they're looking for. I like the uncomfortable, quiet, awkward character development.
