That’s a great example, and I fully agree with you about Tomorrowland. I think it would be much more successful if they streamlined design there. I don’t think it should be nearly as cartoony as it is today.
However, the MCU is the most successful film series in history, and has the largest fandom today. People even outside of the MCU cult should know what these ships look like. To change the color would be PR suicide, especially after the backlash of avengers campus. I completely agree with disneys decision to match the movies.
As for the blue and gold looking out of place in front of the building, we have no idea what the queue will look like. I’m sure the blue and gold will be heavily featured there, just like ride vehicle is blue and gold. Don’t forget we’re judging this before disney has even finished painting the building yet.
I hope you like the final product better than you do today.
