Coraline (background info here) makes my nerd boner swell.  That’s already been established.  All this new trailer does is make it a little more turgid, and give us a little better idea of the plot.  Basically, Coraline discovers a door in the floor that opens a wormhole into an alternate reality where instead of being emotionally absent jerks, everyone loves her.  It’s basically a metaphor for the internet.  I spend my whole life not being propositioned by busty dentists or getting invited to Asian teen bukkake parties, when suddenly I open a series of tubes into a land where I’m in command of multiple, simultaneous Roman orgies.  “Nay nay, the flaccid one displeases me.  BRING FORTH THE EMPEROR’S MIDGETS!”  Yeah… alternate realities are pretty great.
