Jacob Tremblay is really good in this curious, and slightly claustrophobic, tale of a young lad "Jack" who lives with his doting "Ma" (Brie Larson). Nothing odd about that, you might think - well, except for the fact that thus far in his short life, "Jack" has never actually left the room in which he lives. He eats there, plays there, sleeps there - he knows nowhere else. As he ages though, he begins to get itchy feet and his mother finds it more and more difficult to contain his enthusiasm for finding out what is going on outside. What also emerges from their scenario is that "Ma" herself is not exactly free to move about. She was taken by "Nick" (Sean Bridgers) many years earlier and it soon becomes clear that he is likely the father of the boy she is so desperate to protect. Are they better off indoors or seeking freedom? Well, she decides that the latter offers them a better chance of happiness (and quite possibly sanity, too) - but the execution of that plan is not without risk! Lenny Abrahamson directs this with quite a bit of subtlety. He allows the audience to become immersed in the relationship between the two principals; he lets them do the talking and as the narrative unravels we realise that the story is anything but what we may have expected at the start. There is a palpable chemistry between the confident Tremblay and his more experienced co-star, and she complements that well. This is a nuanced and engaging tale offering us plenty of parallels of modern life - good and bad; with a dialogue that is both poignant and frequently heartfelt too. Certainly, it was nothing at all like I was expecting and it's stimulating and enjoyable in equal measure. Well worth a watch.
