Of course it's on the internet. A new episode of just about anything can be downloaded a few hours after it airs. At least I usually get Gossip Girl and 90210 the following day, no problem.
90210 has little to do with the original Beverly Hills. From the old characters, there's just Kelly, and Brenda appeared in one episode as a guest star. But it's okay. Nothing special, I'd say, but okay. And those of us who like teen soaps will like it.
Supernatural… I'm going to buy Season 3 for Christmas, I guess. Season 2 was pretty cool so wouldn't miss that one either.
