Well Firefly didn't really have it easy at all since Fox aired it in the wrong order and confused the hell out of everybody
I think i would have preferred if the FBI guy was introduced later and in this ep we just had the hints of how things aren't right at the dollhouse. Or else the other way round, with him looking for it, going on about it being bad, but us not actually being shown the flaws in their system yet.
I do like the potential implications of the story though, as a psych graduate. What makes us who we are? If you wipe someone's memory completely then is there nothing left of them? Some damage in just the right brain area can change your personality, but are you still the same person?
Of course, knowing how little we actually understand the workings of the brain means having to suspend my disbelief at this magical way of imprinting people with the personalities of others, but i'm pretty good at just treating sci-fi that can't be real as fantasy that i can enjoy
