That's why I watched "Starter for 10", because of James McAvoy and Benedict Cumberbatch.
It's been fun but not brilliant at least not very deep. But you can have a nice evening watching it.
The film is about a boy, Brian (James McAvoy), who gets into college and has to say goodbye to his old friends and settle in in the new environment. To get together with some people and because he's been a fan of University Challenge since he was a little boy, Brian joines the quiz team of the university, which takes part in the challenge.
The set up shows the struggles of the life of a student, not the academic ones, but the ones concerning the private life. And it's very relatable, when you are or have been to university.
This relatability and the funny and also the sad scenes troughout the film make it a good watch, even though you'll know very early in the film, how it will end.
