Cap Marvel looks to be a colossal bomb. Fitting as Marvel decided they hated their fans, but loved ESG. Disney deserves another "L." I hope they sell off their properties to more competent owners.
I see it all as kind of a wasted opportunity if you are going to spend this much money. Two of the major characters are fighter pilots. You also have a multi-verse option to fall back on to create stories that don't impact your "main timeline" Who doesn't love a good dogfight scene?
Put the three major characters into an alternate timeline, where Stark brings back "Jarvis" but not as Vision, but as a quasi human, so Paul Bettany can just play himself and be the villain. Have him kill Stark offscreen ( to write RDJ out), then have him conspire with the Chitauri or anyone else to take over Earth. You'd have a depowered Captain Marvel, with fighter jets and dogfights, along with HeliCarriers in major battle sequences.
I mean this film might be interesting on it's own, with the soft comedy, etc, but my take is when you are under the gun, you don't have much real acting talent, and you are going to spend this much money anyway ( train loads full of cash) then you might as well give everyone a ton of spectacle. You could even bring back the Agents Of Shield cast just to kill them off in a short cameo. Sometimes the family friendly schtick that the MCU rides on isn't giving you the most options. Blow stuff up. Kill lots of people. Have spectacle that opens up all kinds of future merchandising.
Wouldn't it be cool to see a HeliCarrier ram itself on a suicide run to destroy Stark Tower to stop an infestation? Just rain fire and death on everyone. Heroes and bad guys alike. Then Iron Man armors show up and get their lunch handed to them by Justin Hammer's own units of mechs? Think about the toy potential.
Brie Larson is not funny. She's not charming. She's not charismatic. So don't ask her to be that. Just blow lots of stuff up and she happens to be the title character. This is where I vibe with Christopher Nolan. If you are going to spend so much money anyway, then give people something that's true spectacle, that they've never seen before.
