The Overall Reason Why It Rocks
The best part of being an outcast is that it can help viewers sympathize with some of these characters. Some media can make these characters likable in such a way you feel bad for them.

The Only Bad Quality
Sometimes it can be clichéd or badly done such as Gene from The Emoji Movie or Amy from Cuties.
