Honestly?

I don't like Mrs. McCall. I think the sheriff is better than her. I give her credit for being a single mother, but I think she is a poor character and the sheriff deserves better.

I hate her attitude towards Stiles -- her sons supposed best friends. I think she makes questionable choices for/towards her son, and in general. I just think the sheriff could do so much better; and I don't see the sheriff giving up the love of his wife (which is canon) for another woman.
