The other night, I watched Avatar for the second time. I enjoyed the FernGully-esque multicolour of Pandora for the second time; I enjoyed Sam Worthington; I worshipped Zoe Saldana that little bit more, and I thought of how nice life would be if I was a Na’vi, and how far she’s come from being Britney’s sassy little friend in Crossroads.

And now here she is. In her underwear, for a fat paycheque, more notoriety – and what? Le sigh.
