Hmmm... It depends on the move/TV show. There are some moveis/TV shows that I feel should really dedicate time and attention to interesting camera angles, interesting lighting, interesting blocking, etc. And then there are others that I think work fine with the 180 degree rule. I feel like action/fantasy/sci-fi movies with a higher budget should be more creative with the camera while I feel like movies like dramas or plain ole fiction stories can be a little more conventional with the camera. I also feel like lower-budget movies should be allowed to have simpler camera techniques due to having a smaller budget.
I also don't necessarily think that movies/TV shows that utilize the 180 degree rule need to treat the audience like they're morons. One of my favorite movies, for example, 'Night, Mother, is a very intelligent movie. It has simple camera angles and all takes place in one house between two characters, but it's a movie that expects you to pay attention so you can absorb all the rich details of the characters' lives. It has amazing dialogue and amazing acting, too, and the characters feel completely real. It also utilizes a lot of creative blocking so that the viewer doesn't get visually tired of watching it since it does utilize very simple camera techniques and is essentially a dialogue-driven movie. This is a good example of some of the great blocking the movie has:
I do understand what you're saying about audiences not liking to be pushed, however. Audiences will always be attracted to the most crowd-pleasing, simplest movies because humans are creatures of habit and they don't like to expend too much brain power on complex movies/forms of art because they would rather spend that brain power on work/other activities.
