Watcher. It's sculpted in perspective, it boggles the mind how this got accepted.
Blessed of December. The body structure and pose looks really silly IMO.
Johan. Extreme caricature (each foot is about twice the size of his head), which would have been acceptable if every human was sculpted to that aesthetic (while it wouldn't have been a game I would have gotten into, I could have appreciated the effort).
Hannah. The retail model is just plain ugly, and doesn't look nearly as functional as the original. The fact that the original limited model is quite nice also rubs it in our faces.
Steam Arachnid. When someone laid out the sprue for these, one of the legs was copy pasted twice and another was left out. So not really a re-sculpt so much as a re-cut, but I'm guessing one wont happen without the other.
