WHAT I LIKED: 'x+y,' (or 'A Beautiful Young Mind' as it's known in the US) is simply one beautiful and emotionally engaging character study that will have you laughing, crying, tensing and smiling throughout. Few movies capture the magic of so many people whilst still retaining the tension and beauty to keep audiences engaged throughout, but a strong script and great performances help to do this whilst delicately bringing some serious themes along the for the ride.
WHAT I DIDN'T LIKE: The story intentionally ends with much left out, but I'd have personally appreciated an 5 extra minutes to develop things a little more.
VERDICT: A great character study that engages and intrigues more than most. A very, very good movie indeed.
