I liked this episode... it had many elements that were missing form the first six frustrating episodes. I don't mean that it answered any great series defining questions, but rather that it had a good "who done it" mystery and we the viewers were let in on the secret.

also, it gave a sense of nostalga by showing us early scenes from the series, and I like being able to say "oh, I remember when that happened".

and lastly, I liked that we got to explore the perspective of some of those anonymous extras we've seen milling around in the backgrounds while our main characters were deciding what adventure to undertake.
