- Thoughts: It's really easy to show your MC's thoughts (though you have to be careful you don't fall into info-dumping).
- Twists & Surprises: It's (arguably) easier to spring plot twists and surprises on your MC because you only have to give the reader one side of events. Just make sure there are enough clues to justify the reveal, otherwise you're just toying with your readers and they won't appreciate it.
- Character development: It's easier to get readers to connect with the MC because they're getting every thought and emotion as the character experiences it.
Anyway, what do you all think? What's your favorite point of view?
