There's a difference between not being happy with character development (I knew what they were going for with Dean last year, but for me it simply wasn't effective.) and ragging on a character. I see a lot of "Dean only" women ragging on Sam and wishing him away, just as I see a lot of "Sam only" women ragging on Dean and wishing him away.

Frankly, I don't understand either of those mentalities, because I love both guys.
