I just wanted to chime-in that this was one of my favorite shows when I was growing up. I haven't seen it in years though, so I'm anxiously awaiting its release on DVD (no official release date yet, but Columbia TriStar says it's "coming soon").
Mackenzie Phillips was always my favorite, and I was ultra-bummed when she left the series (all three times!
)... so I was really happy for her when she sobered up and straightened out her life.
Looking forward to the reunion tonight!
