Mini Meta 2012

I've been working on these longer than it seems, but here all three prompts are, all on one post:

( I. Usage of other languages in your English fic (foreign characters, emphasis) - getting it wrong/right )

( II. What makes THE movie fandom (big, e.g. XMFC, Inception, Avengers) )

( III. Do you ever come across statements in fic that seem wrong to you, but aren't easily verifiable? )
