I've seen it twice, and I have too much to say about Avatar to get it all out in one sitting. So I'm dubbing this week Avatar week. The first point I want to make is simple: Avatar and audience responses to it put one more nail in the coffin of the myth that speculative fiction is essentially "escapist," at least any more than any fiction is essentially escapist.

Avatar, which may be on track to become the highest-grossing movie of all time, is clearly engaging people en masse. Is this because the economy is bad and everyone wants to get away from the grind of everyday life?
