The story I'm writing right now has several significant characters that routinely interact with the protagonist. The main character has a very strong personality that comes across in the writing, but I sometimes feel limited in what I'm able to write because of his biases. He's an unreliable narrator. While I feel that a perceptive reader could pick up on all the details that hint at what the truth really is, I'm wondering if it would be worth it to switch to another viewpoint every so often. I can write for the other characters without issue, but I'm unsure of how taking the reader out of the shoes of the protagonist will effect how they relate to him. I want the reader to feel like they're coming with the protagonist on a personal level through a part of his life. I don't want to shatter that intimacy by sharing it with other characters. They have distinct voices and views that would hem in on the hero's spotlight. Is it worth sacrificing a little bit of that connection to make the story a little bit more concrete?
