Will Eliza Dushku's new series Dollhouse be a success or a failure like Tru Calling?

I'm a fan of Buffy The Vampire Slayer. I thought Season 1 of Angel was good. I never got into Firefly. It seems that over the year's, Joss has lost some of his magic and good sense of humour. I really hope that Dollhouse is sucessful and what I'd like. Tru Calling never appealed to me, but with Joss Whedon working with Eliza now, she has a chance at a sucessful show. Keep in mind, Tru Calling was on for awhile, so it wasn't -that- big a failure.
