A few more thoughts:
As a poster at TWOP said we were sold a musical comedy and for two acts it was one and then in the third it became a tragedy - a tragedy that felt rotten - now what we want and what we need are two different things - however, I didn't need this, I didn't enjoy it and it ultimately failed to work for me.
JW has lost my devotion - Buffy and Firefly were so great that I have spent my time watching the quite frankly poor Angel in search of those nuggets of cleverness and humour but they are few and far between. If Dollhouse doesn't engage me after several episodes I'll do a Pushing Daisies on it - life is too short to watch material that I don't really like even if it is written by Joss Whedon.
And why was Penny's death so damned passive? Might I be happier if she had died doing something? Might I be happier if Tara had died doing something?
