Well, I hate to bring this up but Doki Doki Literature Club made me realized you can always make a cliche moment and make it really unique. Without spoiling it, there is a movie, I forgot what it's called, in the movie the main character is really self-aware and would look at the camera every time she was going to deliver a line, like she knows you're watching. It's almost spooky at the same time.
Maybe I just look into this concept a little too much. xD
Because one is uncomfortable watching someone, does it entertain another person? It makes you wonder how each person might react differently to the same thing.
And I think it is why horror movies are so scary sometimes, especially in moments when the character is staring into the camera before something bad happens. Or when the ghost/killer also looks into the camera, you think they're aware of you and will come to get you. It adds to the suspense.
I think this is one of the reason why influencers are so big nowadays even though you only get to see this person through a screen you never feel like they're a stranger. The idea that influencers uses the method of knowing you're there is what keeps people coming.
