I like feature-length movies. Short films are a way to fill an idle minute, but otherwise bore me. No one I know spends 2 hours straight just watching short clips or movies on YouTube.
Thats longform/episodic, which is not the same as feature length hollywood.
However you are correct that 8x25 or 6x60 allows for far richer narrative. (The BBC's sherlock is a brilliant example of this 3x90 minutes of tastily thick narrative)
I think that format is in many ways more interesting, as you can develop a story in much more depth than you could with a 2 hour movie.
