Look, I'm easy to please-- maybe you can tell by looking at my fandoms, ha. None of my shows/movies take themselves too seriously, and I hope you won't feel you have to, either.
I like charged sexual/personal tension, basically between any characters. I like OT3s that include everyone in the decision making process (and the porn, natch.) Please don't discount the ladies in a horrible way just to get the guys together.
I like companionship, friendship, and the found family dynamic. Things don't always have to be sunny and beautiful, but I want the characters to stay true to themselves. I love loyalty and affection.
Het, Gen, Slash, any rating, pretty much any pairing-- especially if you can sell it to me believably. Teamfic and people going about being good at their jobs, or spending time building a home-life absolutely works for me as well.
Spelling and grammar are important to me. Not the number-one big thing, but trust me when I say those sort of things make a difference to me.
Beyond any of that: I hope you have fun.
