Last night, Real Housewives Of Beverly Hills, 90210 took a very ugly turn. When we found out that Russell Armstrong took his own life — and that Bravo would be airing almost everything that led up to that event — I was torn. Torn because these housewives had swiftly become my favorite and because it seemed indecent to air the fake events scripted for reality television for the entire world to see. Most of the season was Russell-free, but eventually he crept in, being creepy at a dinner party, making demands at his daughter's birthday party, and half-heartedly going through marriage counseling. But last night's episode was the worst yet — and I'm not sure I can look at these people the same way again.
