Speaking of the Kirby aesthetic (and I do hope they go in that direction), remember all those people who said that film goers would never accept a "giant purple robot" in Rise of the Silver Surfer? So they just loved the idea of Galactus being represented as a gas cloud? Yeah, how did that work out?Will it be more intriguing as a period? it depends if they can nail the Kirby aesthetic and make it different enough from Cap..
Yes, I know Galactus was supposedly inside the cloud - it's still stupid. My take is that if you have one of the most beloved comic book stories of all time (the Galactus Trilogy), you don't have to mess with it a whole bunch.
I don't see why viewers wouldn't accept Galactus. There have been Celestials in some of the other Marvel movies, and some Watchers. I know that movie was 14 years ago, but I still want to say I told you so.
