My interest in The CW’s revival of Beverly Hills, 90210 has been fluctuating wildly with every bit of behind-the-scenes news. Initially, it was very low; we already have Gossip Girl. But then word was that Veronica Mars creator Rob Thomas would be writing it. Interest spikes. But then he backed out because of other projects. Interest falls. Hilary Duff is rumored to be joining the cast. Interest plummets further. Lori Loughlin (TV’s Aunt Becky) is signed. Interest non-existent. But now word is Lucille Bluth herself, Jessica Walter, will be moving from the O.C. (don’t call it that) to the world’s most famous zip code. Interest back. You’re killing me, Buster!
