Jacob Tremblay gives one of the finest child performances of all time.

Rating: 10/10 (20 September 2019)

There is a lot to admire about this film. The direction in the first hour and the final minutes, especially gets the most out of the concept and manages to make a 10 by 10 foot space seem like everything and eventually nothing. Likewise, the direction leaves much of the horror to the imagination and it is all the more chilling as a result. The screenplay is sparse and spartan in the way real life is around such horrific events. I like that several of the tensions in the story, i.e. grandfather's inability to deal with his grandson, are left unresolved. Finally Larson gives one hell of an understated, yet raw, performance that elevates the already strong material.
But much credit has to be given to Jacob Tremblay as well as the director for producing one of the finest, if not the finest, child performances of all time. I haven't seen a child actor as natural and real since at least Justin Henry in Kramer vs Kramer 40+ years ago. Tremblay has no artifice or pretension at all. Jack isn't cloying and so much of the emotional power comes from that character. It would be a remarkable performance no matter what but Jack is a hard character to play. Strictly speaking, Jack is the protagonist and it is his story-the movie at its core is a coming of age tale (abet a messed up one). The scenario that Jack is in is just hard for any person to really sell, let alone a child actor. It is a very good performance.
This is a good movie. It is hopeful in the end but it is intense.
