Except...
Aquaman's success wasn't because "he's an underwater superhero". And it certainly wasn't Momoa's "Aquabro" acting. It was the CGI set pieces.
I'm pretty sure Marvel's effects houses already know how to do those.
I'll be blunt: I have no bloody idea what Coogler will do next. I don't know the man, I don't know how he thinks, and he hasn't dropped any hints.
But I don't understand why almost EVERY idea for BP2 outside this thread (and quite a few inside) is "Marvel will use the second movie to introduce another hero or major villain to the MCU" whether it's Namor, Doom, or whomever they want the 'next Thanos' to be. And yet, I've not seen ANY suggestions of that for the movies that were already announced. Where's the equivalent theory that Namor will show up in Doctor Strange 2? After all, they were both Defenders, right? And they could use Doom too! Triumph & Torment, amirite?
But no, every theory has Strange actually being the star, not just a vehicle to introduce another movie arc. So why in the Hell does BP get treated as a dumping ground for every new guy? Do they think he needs the help? Or that Coogler is so lacking in ideas?
It seems to me that all of these rumors are merely wishful thinking that one favorite arc or another will be adapted... because of all the MCU movies in the last decade, there have been so many. Why, there have been... *carry the 1*
0 adaptations of comic arcs! So naturally the most successuful solo film in the MCU will adapt goddamn DOOMWAR or whatever excuse you have for Namor.
In a few weeks, there's D23. If Feige has any news, it'll be there. It certainly won't be some fly-by-night blog or Youtube channel with "sources" that are probably "that guy at the LCS who says he knows somebody who knows somebody".
