I am going to explain why movies are better alone. First you don’t have to worry, about people talking during the movie. You don’t have to argue on what movie to watch. You could put full focus in the movie. Those are reasons it could be better watching a movie alone.
It could also be better with others because. You could talk about the movie even when others don’t like that. You could see everyone’s reaction, like if it’s a horror movie whether they get scared or not. You could get to know people better on how they react to something major in the movie. Those are reasons it could be better with others.
Though I like watching movies by myself more. I also enjoy watching with others once in a while. Those are reasons of which could be better.
