Top left has a big sarcastic/comedic aspect. He went through dark-brooding like 15 years ago and graduated from that.
Top right is kind of bubbly. ^-^
Bottom left is dark and brooding. :(
Bottom right is too obsessed with his work to brood.

To be clear, I'm all for some 🙂
I'm over how little personally/intellectual diversity that there tends to be in modern TV/movies, and it sounds like there is some which is nice, but it isn't obviously reflected in the poster, so if that's all I was going on...
That said, I have fairly particular taste, and don't know if it's refined, or just annoyingly picky 😁
