It depends on how old you wouldn't want your baby crying while a movie is playing and you would feel the same way if a baby started crying while you were trying to enjoy the movie
possibly if you have no self control you won't get enough air into your lungs and you will black out
They do that to get the babies to clear out their lungs. crying is good for babies, it strengthens their lungs too. just don't let them cry too much!
