I picked up the Brady Christmas DVD last month (it was finally released separately). I hadn't seen in probably 20+ years. Honestly, I didn't enjoy it as much as before. It is nice nostalgia though, but otherwise just so so. Clearly with it being huge in the ratings, it set up the idea of a new series. Since the series didn't do well, it seems that they should have continued with specials. That likely would have had continued ratings success, at least for the short term and sadly that's really all the time would have allowed anyway.
Guess what I just found at Goodwill! Maureen’s autobiography! (Along with a Roger Moore and Mary Tyler Moore book)
