You know what kind of commercial we don't see anymore? An ad for a movie or a play that consists of a bunch of "civilians" outside the theater raving about what they just saw. Spots like this one for the 1979 film The Champ:
It's even better with a movie because you know they could show actual scenes from it but instead choose to show moviegoers telling us how good it is. I want to see more of this kind of thing. Instead of trying to wow us with spoilers of all the cool shots and stunts in a big Marvel movie. just have ham-and-eggers outside the multiplex, literally wide eyed, declare, "It's the best one yet!" "I've never seen anything like it!" "I can't wait to see it again!"
After all, elite Hollywood types will try to snow-job us, but real people who pay for the movie won't let us down, right?
