Does anyone else sometimes think that maybe Marvel in general isn't the best property for a theme park?
I've probably posted this before, but the predominate theme of most Marvel comics for the majority of their run is the interjection of extraordinary people into modern, if unremarkable settings, usually New York. This might make for a good film, and obviously makes for popular comic books, but I'm not sure it's ever going to translate especially well to a theme park area, where place, rather than story or character, must naturally be king.
Just thinking for a bit, ARE there many locations in the Marvel universe that would make for good theme park areas? Other than a new specific buildings, like the X-men mansion, I really can't think of many. This is probably why the Marvel area at Universal is such a disgusting, frightful mess, even if the attractions are excellent.
I'm not in any way in favor of even a temporary overlay to ToT, but I do think you are wrong about Marvel not having good locations that would be interesting in a theme park setting. Here's a small list:
Wakanda - A kingdom in Africa ruled by the Black Panther, thought to be one of the most advanced civilizations on earth, though their tech is cleverly hidden in what looks like traditional African art and architecture.
Attilan - Hidden city of the Inhumans, sometimes located on the moon.
Asgard and the Nine Realms - Realms of the "Gods", trolls, giants, fairies, dwarves, fire demons, etc. Based on Norse Myth
K'un-Lun - A mystical kingdom hidden in Tibet, similar to the myth of Shangri-la.
The Microverse/Quantum Realm - An entire universe discovered when Ant-Man shrinks to sub-atomic levels.
Madripoor - An island nation that is known for being a hive of villainy, corruption, and piracy.
The Savage Land - A land that time forgot, full of Dinosaurs, cave men, lost alien temples, Atlantean cities, mythical beasts, megafauna, and a Tarzan-esque character called Kar-Zar.
The Dark Dimension, Nightmare World, Dream Dimension, etc. - Countless bizarre dimensions explored by the Sorcerer Supreme, Doctor Strange.
Atlantis - Is any explanation needed?
Cosmic Universe - Alien worlds on top of alien worlds, all strange and colorful, Guradians has only scratched the surface.
And many, many more. The Marvel universe is boundless, and part of me would like to see WDI tackle it uninhibited by what's popular, profitable, or best known, and also not tied down to exactly how things are in the movies. However, they should give their shot at a self contained park of its own, give it room to breathe and not wreck things in other parks.
As a side note, I hear a lot of mention of ToT somehow being made into "the Collector's Mansion". Perhaps I don't know enough of the Collector's history, but I'm not familiar with him owning a human mansion? In the movie he has a base/museum inside the severed head of a god-like alien called a Celestial. I'm sure that wouldn't look at all out of place at the end of Sunset Blvd.
