What I mean is, should everything relevant should be explained in a story ? Or should some thing be left to the imagination to keep the reader wondering ? I can be related to the story or to character. But is it okay to not explain things for the reader to fill up the blank himself, or should the writer explain everything ? Exemple : The Midichlorians in Star Wars, The Force was something mostly unexplained but Lucasfilms decided to give a scientific eplaination to rationalize the concept of The Force. But was it for the best ? Or in the game Silent Hill 2, the main character wonder in a town and sees monsters with little to no in universe justification. The story team originally decided to explain this by having the character be schizophrenic. They eventually backtracked and didn't gave any explaination so the player can put himself in the characters shoes more easily and have him fill the blank himself. To make the player use his imagination. I read that stories that leaves just some little things to the reader's imagination are usually better received. What is your opinion ?
