Actually I hate tennis. And this movie shows so much tennis, that I should actually hate this movie as well.

But this movie was so thrilling, even though it shows so much tennis, it was so interesting, it kept me on the edge of my seat, that I have to give it a great rating.

Both actors are incredible. I never saw a Shia LaBeouf movie I liked - this is the first where he actually shows what an incredible great actor he is, and that he has to offer so much more than the mediocre acting we know from the Transformers franchise. Sverrir Gudnason I have never seen before and I cannot understand why this guy doesn't have a lot of hollywood projects in the pipeline. The acting is superb, and Stellan Skarsgård is a great supporting actor.

This movie is a great character study, showing how two characters who couldn't be more different are actually quite similar, as they have a similar struggles, even as children - where different paths led to different personalities. And they still struggle with the same problems, they have the same desires, the same pressures to deal with, the same problems. They deal with it differently on the outside, but they are the same on the inside.

It is a well acted, totally thrilling story. It's worth watching, even though it is a nieche movie. Worth your time!
