Sometimes, its the little things that often get overlooked. I like to see wiki pages and famdoms flushed with rich detail and trivia most people wouldn't notice. If there's a reference, an in-depth analysis, even a line that slipped by that could give more life to a character, I want to see it! Minor characters don't get the spotlight, so when they get the chance to shine, why not give them all the love they deserve?
If I browse by and see a page needs some more detail, I'll end up rewatching the movie or scene to find something new to add to the conversation!
