Today's story telling involves a lot of multiverses, dimensional, parallel universe. Usually happens in comics, science fiction stories. It can be interesting at first but too much and too frequent uses makes these plots as bland and add to confusion. Take DC comics, they have been using the multiverse elements in their comics and TV shows. While the TV shows will take them based on the comics, it adds to confusion to new readers or audiences. You never know when you flip open a Superman comic and saw there are multiple Supermen, in a different costume design or race, age. You will be forced to read from issue 1 to get to the reason of the event and you will kind of lose interest in all these hassles.
