Season 1 - A Swing and a Miss; Season 2 - better... I am a big Joss Whedon fan, and Dollhouse makes me sad. He seems to have had lots of cool ideas swirling around in his head, and failed to synthesize them into a decent show - at least in season one.
In the beginning, the premise of the show is "Dushku is hot, and we don't have to be bothered with her character, because we'll just write a new one every week. She can be Hot Archery Hunter in the Woods, Hot FBI Agent, Hot Blind Girl in a Cult." Nevermind that this character must have once been a person, and why is she here, and what are the free will considerations, and if she is programmed to want to have sex with someone, is that rape? etc, etc, etc.
In season one, there is one episode that points to some deeper issues. Once a year, a man hires her to play his dead wife. He had thought of himself as a failure, and on the day he sold his invention, and finally got what he was working for, his wife died before he could tell her.
In this episode, Joss dealt with needs, and how we all need things from each other. Even the people we love are important to us, because of how they make us feel. So where are the lines between love and using someone.
Ah well. In season two, the show did a 180 and started to explore identity and free will, but by then it was too late.
