However, I thought it was interesting enough to watch again for a few weeks at least.
I liked the way they clearly introduced the well known characters. They didn't exactly show up with big name tags, but it was very clear. They're all there. Updated & modernized to CW's idea of modern teens. Their personalities meshed well with the way we all grew up seeing them.
One big surprised & HUGE disappointment: Miss Grundy is quite young, hot, and a slut who has sex with her teenage students. That part put me off big time. For anyone who's raised teens, that is disgusting & extremely negative. Teenage attracting for a teacher is common, but those teachers who do that are pedophiles. YUCK!
All in all, casting was pretty good. The mystery has potential & there will probably be more.
