So no one likes the switching of POVs in books, although a few of the Harry Potter books switch after the first chapters. However, I noticed that in many movies and almost every TV show, POVs are switched constantly. I also noticed it in two of some of the most popular Disney classics, Aladdin and The Lion King. Many of us probably know who the MC's are. Aladdin is obviously the MC of his movie and Simba is the MC of the Lion King, although in nearly half of The Lion King and even Aladdin, the scenes were NOT from the MC's POV. In TV shows like Family Guy, where Peter is probably the MC, many scenes aren't from his point of view either.
So that's okay in movies and TV shows, but not in books. I am asking because in my second book (related to the one I am currently writing), I have a plan for my MC to fall unconscious and disappear somewhere during that (I've written about 2 or 3 drafts and took a break from it). So I will have to switch POVs for one time. What will that do to readers, though? I've sometimes switched POVs without realizing it. But if it's obvious, will that confuse readers, even if I have no choice? Why is it not normally okay to switch POVs?
