Many will disagree, but Disney has DEEP content to mine with Marvel. I realize they have produced a lot of content, but I have no doubt there are other $1B film franchises lurking in the vast library of Marvel characters. That could easily lead to new attractions. That said, what Disney has done so far on the west coast with this IP is disappointing. Although I think they managed to improve the Hollywood ToT by retheming it to Guardians (it really is superior), I have always felt they could, and should have made an original attraction. Then there's the supremely underwhelming Avengers Campus which wasn't even fully built out. There is a large structure for an E-ticket attraction with nothing in it. I have visited Avengers Campus and feel Disney really "cheaped out" here. Consider the rich and immersive detail in the Star Wars areas, not to mention Cars Land (an amazing space to play in). I'm sure Marvel is on a par with Star Wars in terms of film receipts these days and yet Avengers Campus is a joke.
