For starters, Grandma took him to see Avatar, a flick I would not have allowed him to see (and did she ask me? no. Bad Grandma, Bad!) Although: no harm done, apparently. I was expecting it to be Sex On A New Planet, but Steven Greydanus says it's okay on that score; even better: EW didn't like it all by himself.
The Grandma/EW review, phoned in by EW.
Grandma: fell asleep.
EW: While I have to admit I did enjoy the technical aspects, by the end I was almost asleep.
