Big Whedon-admirer myself.
Think Firefly didn't succeed because it was too episodic. All the new trend-setting major shows opted for stronger seasonal story arc. Loved it anyway.
Now for the film/TV/web speculation. Even with the bound-to-happen convergence of media, there's still a need for different formats, the feature-film stand-alone drama, the TV-show's more novel-like continued drama and the shorter, episodic, often comedy based web/sit-com format.
I wonder a bit about the nature of Whedon's talent. I am not sure he is a feature-film man. With especially Buffy it seems like he thrives on universe-creating and the continued relationship with audiences, the playing to and against expectation.
Serenity was a good script without any obvious faults. But I lack a sense of the definitive monolithic quality a major feature film should have. That said, Serenity was still better than most of the entertainment-crap posing for films.
