I saw the new NBC app on my 3rd generation Apple TV home screen a couple of days ago, and it appeared to have full TV episodes of their latest shows.
Checking season 3 of The Blacklist, I was bummed the first episode was no longer available. I rented it on Apple TV, then watched the second episode in the NBC app.
Observations — I’d mute the TV during commercials (between 60–120 seconds). There was a weird block of commercials between the final scene and credits. On the other hand, maybe it makes sense when binge watching, because the start of the next episode is immediate.
Overall, all went well, and I’m on my way to catching up. Nifty to have another option.
