It just came out on DVD here.
I liked it a lot. I thought the stars were both great and so are the supporting cast. I guess I'd query Radha Mitchell's voice quality, she has NT voice quality, very clear and precise, but I think she's the higher functioning character out of the cast and hey, if everyone shouted or mumbled no-one would want to see the movie.
I was glad they kept it short-ish and I can understand why it may have been re-cut. It just wouldn't work as a long film.
I think it's to be commended on many levels. It's our first movie about people like us, so what's not to like?
