One weird thing about the MCU now is that there are more superheroes than ever, but I have almost no idea which of them actually know how to contact each other.
Not whether they've met. Literally whether they could call each other.
The first Avengers movies had SHIELD doing a lot of invisible logistical work. Fury knew where people were. Natasha could show up. Tony had everyone's information. Later Steve had his own network. Even when the movies didn't explain every connection, there was a believable structure underneath the team-ups.
Now that structure is mostly gone.
We have Sam Wilson, Shang-Chi, Wong, Doctor Strange, Spider-Man, Daredevil, the Wakandans, the Fantastic Four, various younger heroes and several people who have crossed paths with one or two of them. But sometimes it feels like everyone exists on a separate island until the plot decides a crossover is happening.
I genuinely think five-minute scenes of mundane connection would help.
Sam gives someone his number after a mission. Wong tells Shang-Chi who to call if the rings start doing something weird again. Kamala gets introduced to someone through Carol instead of randomly meeting them during the next emergency. Somebody mentions that they already spoke to Banner last week.
Not every connection needs a cameo. Sometimes a name in a contact list is enough.
The original MCU became interconnected partly through big post-credit reveals, but also through boring connective tissue: SHIELD files, phone calls, brief conversations, people having mutual acquaintances.
With Doomsday bringing so many characters together, I'm almost more interested in seeing who already knows whom than in the first big fight.
I want one scene where somebody says "I'll call Sam" and another hero responds "Wait, you have Sam's number?" That would make this giant universe feel smaller in exactly the right way.
