I saw "Epitaph One" as the future they were trying to avoid, so I was kind of surprised and a bit disoriented when they ended up there anyway. But then "Epitaph Two" handled it in a satisfactory enough way, and was interesting enough on its own, that I didn't mind much.

ITA about any S3 having nowhere to go but off the rails, tho. It might have been interesting, but it wouldn't really have been Dollhouse anymore. I loved the show, but felt quite satisfied by the amount of it we got.

Sometimes a story is just done. The US model of series television isn't very good at getting people used to that idea.
