This may be an old-fashioned bio-pic, but there's nothing terribly wrong with that. It's subject is intriguing, the story it tells is emotionally engaging and - unlike so many recent, showier bio-pics (The Imitation Game springs immediately to mind) - it doesn't play so fast and loose with the facts that you're left questioning whether it was really worth the effort. It's slickly directed and boasts a cast of extremely fine actors, among them Victor Garber, Hope Davis, Jefferson Mays and Sarah Paulson. But the two main reasons for watching are Nicholas Hoult and Kevin Spacey. Hoult gives his best performance since A Single Man, while Spacey (as Salinger's teacher and mentor) pretty much steals every scene he's in. If recent revelations result in Spacey being forever black-listed by Hollywood it will be a great shame.
