I loved every second of it and I wished they had gotten to this point in the actual series, or even set the series in this time with flashbacks.
I loved how the characters developed, Adelle and mad Toper. The kind of redeemed Alpha (I would have loved to see that story unfold), the techheads and even Echo and Paul. Never thought I could get behind those two, but by the end they had me there.
Also loved Echo's breakdown when she talks to Pryja about Viktor, it felt like what we never got from Buffy over Spike's death in a way.
I'm really sad to let Dollhouse go, it was a fine show with lots of lost potential through bad timing. In retrospective it feels like there are about 5 eps with the right tempo, the rest was either too slow or too rushed. But anyway, I'm glad that we got what we got, it was intriguing concept and an amazing show.
