Well, really, that's what we're getting with these shorter seasons - all the plot based stuff and none of the other stuff. But, the other stuff is really where Star Trek developed so much of the character and world. That's where the Holodeck episodes lived and the more character driven stories where Worf or Data ponders their particular existence for an hour.
The new format is more along the lines of a really long movie. They remind me of the old 80's TV Mini-series that we used to get. Things like Shogun or various other, basically, 10 hour movies. You just don't have the time to develop characters like you could in the older series. You can't spend an entire hour on Odo trying to turn himself into bird or whatever.
I really wonder if that's what turns people off from the newer Trek.
