Couldn't agree more with everything you said. Even the opening of Inglorious *******s is 23 minutes of essentially two people sitting in a room - yet it's riveting.
Personally, I still found Pedro's Joel to be deadpan, lifeless, and dialed-in.
Bella was okay... okay at best. So many weird things with her character that amounted to nothing as well. The scene where she stabs the infected in the head like a psychopath??? Ooooookay... How did that affect the story or add anything worthwhile?
So many little things that make worlds of difference were neglected.
Well here's a different angle to things.
Let's say Mazin and Druckmann were dead set on not having much in the way of Joel/Ellie interaction. ( We get snippets here and there, but that kind of bonding IMHO takes time)
- Marlene/Fireflies Vs FEDRA
- Kansas City Resistance Vs FEDRA
- How Tess joined up with Joel / Tommy
- Early days of Joel/Tommy after the outbreak
- Frank's story BEFORE he met Bill
- Henry's conflict with the Resistance in trying to save his brother
- Maria and the Dam/Hydroelectric settlement and how it started
- More exploration into David's totalitarian settlement
- The FEDRA school
- The friendship of Ellie's mom and Marlene both before the outbreak and after
So many different storylines that could have gotten an episode, to flesh out the world building. Lots of interesting stuff that had potential for limited violence on screen.
I'm a little hesitant to say Pascal and Ramsey didn't deliver, in so much as IMHO, I felt they were probably miscast for this show. (That might be a controversial take to some, but it's my viewpoint) Also some of the writing did them no favors. Also both parts are incredibly complex parts given the situation they are in and the kind of depth they have to convey in only a few short scenes.
Something I've always seen as a litmus test on narrative "bloat" is start seeing what scenes or characters you could remove and that surgical cut would have no impact on the overall story at all. For example, Melanie Lynskey as Kathleen, the leader of the KC Resistance. I didn't find her particularly compelling and her scenes didn't really further much in the way of Joel/Ellie. If you cut out her handwringing and puritanical streak, I don't think much would have been lost. So I agree with you that each scene has to be weighed against it's value for the end goal of the story or if it's just excess.
A good crossover example are films like Terminator 1, Predator 1 and Die Hard 1. All those films are extremely efficient. Each scene matters and it's there for a reason and there's nothing really extra. If you start trimming out scenes, you start to see how the entire package starts to fall apart without them. Predator 1 is extremely lean in that regard.
Look at Rings Of Power. You could start trimming out multiple characters and scenes and it wouldn't make a ton of difference, so it's a strong sign why that series was critically panned for having a poorly structured narrative.
But again, some people really loved this season and some people loved the casting and the way it all ended up, and I'm happy for them. It's not entirely my cup of tea, but if they want seconds, then that's great too. I loved Stargate Universe and some people think it's the dumbest show ever, so we all like different things.
