The highest compliment I can give "Room" is it's the hardest movie I've watched in a long time. Hours after it was over, my nerves were shot, emotions drained. It really got to me.
The screenplay is by Emma Donogue, based on her best-selling novel. It's a wrenching drama about a woman held captive for seven years in a garden shed with the five-year-old son she had from the rapist. The boy, Jack, knows nothing of the outside world, and his Ma tries to protect him from the regular horrors visited on her from the madman.
Saying more would be giving too much away, and I'd encourage you not to watch the movie's trailer because it's loaded with spoilers. But what I can say is the second half of the movie is an entirely different yet equally harrowing emotional journey.
Brie Larson is wonderful and will win an Oscar for her work, and young Jacob Tremblay is a revelation, delivering the best performance I've ever seen from a young actor with exceptional range and nuance. He won a Critics Choice award, and he should have been Oscar nominated.
My one criticism of "Room" is the score, which tries too hard to tell the audience how we should be feeling. It's not necessary. "Room" is a harrowing viewing experience with acts of astonishing evil and chilling cruelty but also amazing kindness and love. It's an expertly acted, elegantly directed picture. And I'm not sure I could ever watch it again.
