What it was about (in > 75 words)
As a result of rape and abduction 7 years ago, Ma (Brie Larson) raises 5-year-old Jack (Jacob Tremblay) within a locked up 10'x10' windowless shed (Room). Their only window to the real world being the skylight.
They plan a risky escape by convincing their abductor, Old Nick (Sean Bridgers) that Jack is seriously ill.
I didn't realize Jack was a boy till much later as his name wasn't mentioned early on in the movie. I had genuinely thought Jack was a girl as his hair had not been cut in a very long time.
The performances delivered by both Brie Larson and Jacob Tremblay's were highly commendable. That's possibly why this film received so many accolades (besides the script, direction, etc).
Despite Jacob Tremblay being just a very young boy (between 6-8?), his and Larson's acting convey a very realistic relationship between mother and child, Kudos to both of them.
Waste/worth the time?
Dark, touching, suspenseful and deeply emotional. It's not the typical Hollywood fare. Viewers need to be prepared for an emotional roller-coaster ride as you WILL care for the characters and what happens to them as the movie progresses.
I will definitely recommend that you go watch this film and I would also want to watch it again sometime in the future. Probably after I watch Brie Larson's interpretation of the titular character in next year's Captain Marvel (Yes, Super-Hero fans - next year...).
