My partner and I have recently been watching Joss Whedon's Dollhouse.
Firstly, we can see why a lot of Whedon fans might be disappointed in it. It doesn't carry the same sort of 'flavour' as previous works. Buffy and Firefly had a fairly strong sense of adventure. Dollhouse doesn't have that.
But there's actually nothing really wrong with it. We started watching with no preconceptions as to genre or style, and we've so far been very impressed with the results. It's complex, dark, morally ambiguous, and the cast is doing a tremendous job.
It's got to be hard for Whedon. We think Dollhouse has an awesome flavour, but if it isn't the flavour you are expecting you can be disappointed. Roast beef and chocolate are both great flavours, but if you get roast beef when you're expecting chocolate, that's going to be somewhat offputting.
We, personally, are enjoying it hugely. That doesn't mean you will, or that you should. It doesn't mean that you're not being fair to the series. This sort of thing is hugely subjective and what you think about the show is no less valid than what I think about it.
If it's something you like, though, or that you want to see continue, there's a twitter campaign to encourage Fox to go with Season 2. Thanks to the charming Felicia Day for the heads-up.
Dollhouse. It's not Firefly, but that doesn't mean it can't be satisfying in its own way.
