I still have soft spot for this two-parter - it was one of the few episodes that my library had on VHS when I was first getting into the series. Yes, in the grand scheme of things, it sucks as a season ending cliffhanger.
It has some good moments though. When Data's head was found under San Francisco, I wondered what the hell was going on. Data going on to hussle his way into some clothes during poker was quite funny.
I love how paradoxical the Guinan/Picard friendship is too. Each one already knew the other when they met.
