Echo is a member of a highly illegal and underground group of individuals whose personalities have been wiped clean so they can be imprinted with any number of new personas. Confined between missions to a secret facility known as the Dollhouse, the "Actives" are hired by the wealthy, powerful and connected to wholly become—with mind, personality and physiology—whomever the client wants or needs them to be. They know no other life than the specific engagements they are in at that time—or do they?
Dollhouse is an odd show, it took a few episodes to establish where it was going and once it did cancellation was just around the corner at the end of its second season. So, is it good? Yes, yes it is, the concept of blank slate people implanted with personalities is science fiction gold and is used in a few interesting ways by the writing staff, also the characters are well developed and as an audience they are easy to emotionally invest in. The ending is a bit of a mess but its still worth watching. Also "Epitaph: one" is a 10/10 episode of science fiction.
