The problem with the show is that the stakes never felt that real because almost every.single.death.on.the.show.was.undone. Seriously, what is that? I didn't even feel bad for Nick and Sabrina because I figured that at some point in this universe they'll be resurrected and we just won't see it.
The closest this show ever got to making me feel any kind of sadness was when Sabrina kills her Plant Clone, and Harvey's brother. Otherwise the show lacked any real emotional core.
It was a fun trifle for the most part, but it just never reached the heights of Prime Era Buffy (season 2 through season 5), which managed to balance humor/campiness with emotional pathos.
