A film about maths nerds and autism, rather well done; had to choke back the odd tear. The protagonist is a maths prodigy and ends up competing in the International Mathematics Olympiad. Nice depictions of relationships between nerds, male and female nerds, and savants and their parents. A few actors usually seen in Mike Leigh films (Sally Hawkins, Eddie Marsan, and I think Rafe Spall) give great performances.
Nice footage of Taipei; small autobiographical note, I spent some time there during the Ovum Asia Pacific tour a few years ago and found it a surprisingly pleasant place. Several of the places I visited (the big park, the night market) were in the film and it was nice to see them again.
