You pay $40 a person to look at costumes behind glass, which are for the most part high up, with graphics on the glass that obscure your view, and the whole thing feels inauthentic and far removed. Also, there's an app that takes a while to download and uses tons of memory and none of the people in our group felt like it added anything to the experience. Finished by a lame 5 minute video game.
I would've enjoyed reading some interesting facts about the movies, behind the scenes stuff, etc. like you'd have at most other exhibits. Personally I felt that this experience was worth about $10 and I love all things Marvel.
Side note: Why does this business insist on responding to reviews with that lame canned response? Just accept the feedback and use it to make the attraction better!!!
