I'll respectively disagree on some points.
1. Spiderman is an okay ride. Definitely not one of the best.
2. I have to believe if Disney were to fully recreate current MCU , it would be nothing short of phenomenal. Maybe I'm crediting Disney too much, but there is no way they can do anything less than what we have now, aesthetically.
Now what do they create to anchor a land or ride stories? Who knows can go a number of ways but I suppose this new guardians ride would give a preview of what we could expect if it does happen where Disney has that opportunity.
As it currently sits, Hulk is one of the better themed coasters there is, especially for a superhero. It has a story line in the queue that follows up to the actual ride. That is awesome. That energy is the same energy that would need to be in any MCU additions at Disney. Spiderman has that same thing going on too.
I'll hope things change among the messy situation with contracts one day. Who knows, WB, has a good relationship with Universal already, we'll see Scott.
