Despite my best efforts, I'll admit it: 90210 has sucked me in. I'm not proud of it, but CW just has a way of doing that to me. 90210 isn't a great show: the acting is so-so and the plots are completely predictable . Nevertheless, every week I find myself inexplicably drawn to the goings on at West Beverly High. Apparently it's not just the audience who's getting sucked in: the actors are as well. Despite sounding like she wasn't interested in appearing beyond her initial four-episode run, Shannen Doherty is returning to 90210.

Doherty has signed up for two episodes of the CW series with the possibility for more. Doherty has been joined on the 90210 set by her costar on the original 90210, Jennie Garth. Both of their characters left town in a recent episode, but Garth has always planned on coming back. After all, her character, Kelly Taylor, is actually employed at West Beverly, while Doherty's Brenda Walsh seems to have come back solely to react to Kelly's storylines and babysit her son.
