I remember seeing the first Guardians of the Galaxy movie, and thinking what a good solution it was to have Star-Lord's mask appear and disappear with a click of a button on his neck. I could accept it with alien technology and it meant we could see the actor's face more. Marvel, however, has really taken the idea and run with it. Now it seems like everyone has these magical types of helmets. Iron Man, War Machine, Ant-Man, The Wasp, Spider-Man, Captain Marvel, Black Panther, Yellowjacket... pretty much anyone who wears a helmet seems to have access to that movie-friendly yet improbable tech. I love the movies, but that's always been a minor nit pick for me.
