I liked This Is Us last year and have been saving the new season to binge. I've watched 5 episodes in a row today. What I didn't notice last year, but is easy to pick up on during a marathon session, is that every episode follows the exact same formula.
1. Cute, playful jokes.
2. Awkward, embarrassing or upsetting situation.
3. At least one character showing growth or compassion.
4. Tear jerking resolution.
Boom! That's it. And I know this stuff is in lots of dramas but with this show it goes in that order every single episode. Go watch a random episode it will unfold like that. But it works because there is such a large cast they switch up who is involved in each scenario every time.
