Best Use of Sex to Show Character (As Opposed to Sex to Show Sex. Not That That's Not Good, Too.): Silence, by Cinzia. Lord of the Rings, Aragorn/Boromir. Yes, there's angst, but it turns out angst works on Boromir.
Best Imitation of the Canon Author's Voice: Influence, by shalott. Master & Commander, Aubrey/Maturin (of course). The author just nails Patrick O'Brian's voice, although I can't imagine him ever putting it to this use. And Maturin and Aubrey could not be more in character without, you know, not having sex at all.
Best WIP Fic (While Fully Acknowledging That WsIP Are Evil): Jjail, by Firesignwriter. Pirates of the Caribbean, Sparrow/Norrington. The reason I read PotC (despite my revulsion for what most people consider the OTP of the fandom) is that the fics are fun. Less angst, more humor; less moody, sullen, repressed cavemen, more swishy, pansexual pirates; less use of the word "despair," more use of the word "savvy." This fiction, despite being a possibly-abandoned WIP, and despite containing several things I don't generally like to see in FF, is an excellent example of the genre.
