The first two episodes were ...interesting I guess. The paranormal stuff dominated the episodes a bit too much for my taste. I preferred the way it was in the old series, when that was part of it, but secondary to the quirky characters in the town. And I also hated the CGI.
I've done my best to avoid spoilers, cause I didn't want to know which cast members were returning until I saw them on the show. It seems like most of the ones who have shown up so far were only onscreen briefly, with most of the shows focus being on the new characters. I hope the returnees aren't relegated to meaningless cameo appearances.
