Truly, truly, I was even more surprised when I saw how much was "revealed" in this particular sequel; sorry no major descriptions--instead I highly recommend that you see this for yourself. Thought this was a fine ongoing continuation of "More tales of the City" which opened some doors that were promptly closed within this sequel.
You have to start at the beginning, so I'd suggest watching Tales of the City and More Tales of the City first. These mini-series are based on a six part series of books by Armistead Maupin.
Many people said that this time around, it was much darker and downright dreary. Yes, it was darker, but the times were darker, too.
