X plus Y (2014)

"It’s the little things that make characters feel real in James Graham’s X+Y script, which portrays autistic hero Luke as a person, rather than a pick-n-mix of “disabled genius” clichés. As the math-obsessed, socially awkward teen, who confesses to seeing the world “differently”, Asa Butterfield is superb. Following the death of his dad, Luke is inspired by his MS-suffering math tutor, (a suitably cynical Rafe Spall), to compete in the International Mathematical Olympiad (an Olympics for math - who knew?). As Luke’s long-suffering mum, Sally Hawkins conveys subtle grace as he rejects her touch, or demands his Chinese take-away contain a prime number of prawn balls."

"A fiction loosely based on fact that adds up to a satisfying, compelling drama."

"With A+ acting, a solid script and sensitive handling, there's enough here to move even the hardest of souls."

"At the core of this tender-hearted and moving British indie film is a fascinating relationship between a single mum and her autistic teenage son."

"The film's magic is how it slips the skin of sappy and mendacious formula, stepping away from cliché scene by scene, and in quietly revelatory ways."

"[A] deeply affecting, sensitively handled British drama."

"Familiar formula yet Morgan Matthews' feature debut adds up to a satisfying whole."
