Looks like you can watch Yahoo Screen on screen.yahoo.com, download an app on iphone or Android, and even my Vizio TV has the Yahoo Screen app. What's great is they released the episode early so you don't have to wait for 7pm or whatever crappy time NBC used to put Community on.
It thought it was really funny. The montages were great. I kind of figured I would be seeing the person at the end segment before the credits and the knock on NBC was funny like the season finale of Season 5.
I think the second episode was mostly for introducing the new cast member. Keith David's a good choice, especially after the roster was so depleted after the last season. I also kind of appreciate what is, for Community, a more grounded episode dealing with some of the individual characters, since the first episode was a little more meta than usual, even for Community.
I enjoyed both episodes immensely - and maybe I'm projecting a bit, but the show really did have a feel of being relieved from the constraints/pressures of NBC - even if the content itself did not take advantage of the lack of FCC regulations.
Yahoo Screen really, REALLY needs to get a dedicated app on either Chromecast or the XBOX One - and it's a little shocking they weren't able to roll one out ahead of this big debut.
