Ironically, Joss Whedon had done interviews at the time of
Serenity's release about wanting to avoid exactly this scenario, and although he didn't 'name' his examples, he did mention past TV-to-movie translations that he felt dropped the ball by failing to suitably change out of TV mode. I've always felt he was making a veiled comment about Star Trek when he said that...
...which is funny, as I think of all of the Marvel movies,
The Avengers is the least cinematic in feel, and it was made
for the big screen.
One thing I took away from the DVD release of
Serenity is that I think, while Joss was clearly thinking 'bigger' than TV in terms of the story, he was evidently having a lot of trouble putting his mind into movie mode as opposed to television. Many of the deleted scenes from the movie are either talky exposition scenes or 'character moments' between Mal and Inara that would have been like cream in a TV show where there was time to explore the character dynamics better, but which was dead weight in a movie where everything had to keep moving to sustain the drama.
This is fascinating, because there are probably parallels there with, for example,
Generations, where Moore and Braga were probably still pitching a movie length television episode, and a lot of the adjustments to make it more 'cinematic' came from outside influences (like the cinematographer lighting the sets differently, or other things like that).
First Contact was shot by Frakes in a very television manner, nailing the schedule down and shooting a lot of things very fast, but the script was much more tailored towards movie storytelling to begin with. One can actually imagine
Generations and
Insurrection being filmed as these kinds of extended length TV episodes and not being very different from what we actually got, but
First Contact and
Nemesis have got an inherent 'movie-ness' to them from the very core of their stories to begin with. They think 'bigger' and act 'bigger' from the outset.
