I think there's a point where things can't shrink anymore, and 10 mins (or less) is that point, at least for dramas. Comedy of course lends itself well to the format since there's standup or improv sets, as well as scripted skits that easily fall into that time limit. But Dramas... I don't know. It's hard to get across a satisfying amount of character development, action, and plot progression in only 10 minutes. I do see people complaining about longer seasons now, but not longer episodes. People were more than happy with the 60+ minute GoT episodes, for example. And if anything more and more shows have trended in -that- direction as most programming now doesn't have to accommodate for commercial breaks and the ~42 mins that locks you into.
This all being a cash grab for Katzenberg aside, I don't really see the model working well (at least with drama)... even moreso given that the majority of these shows are features chopped up (which goes against how they have been conceived). I just don't see a world where kids are watching an episode of something on Quibi on their way somewhere over checking their socials. And if they're sitting down to watch a show, they probably are going to be in for something longer than 10 mins.
