Stefan never should have been created, let alone resurrected.
Sloan's story is as idiotic as her eyes are expressionless.
I might have liked Alex if he didn't dress like the worst version of Sonny and have those stupid glasses and dumb speech mannerism (which comes & goes based on how much attention the actor is paying to his glasses), and if they'd made the effort to separate him somewhat or explain his looks (e.g., give him a fake nose and a blonde wig for a month until gradually the actor works without makeup) so that he could mingle in the same crowds as Ben without idiocy.
I've been done with Chad for a long time, although I think Billy Flynn is a fine actor. I didn't like Chad Peterson-Woods or early, Melanie-frenching, tumour-faking Chad, either; but when he stalked Ben and boinked Jordan out of hate, I was through with him as a useful character, especially now that he's portrayed as the "good" DiMera and a "hero".
That said, Paulina's story appears to be done, so they need to get her a friend that's not married to her or biologically related to her (or dead). I like the actress and the character, but her stories have been moronic and/or half-thought-out (remember the "Price Town" Square takeover?).
