Room Intense; particularly the first hour where the reality of the situation gradually unfolds (helps if you know nothing of the story in advance, and I mean nothing) At times it's not an easy watch (the grainy film gives it a realistic edge) but it is an uplifting story with an optimistic message, even if there might be professional opinion that could challenge that. On rare occasions, it does come across a tad trite and that does diminish the power of an otherwise excellent film.
Most notable for me was the performance of the 5 year old boy, from whose perspective the story is mainly told. That perspective in itself is revealing, and asks many questions, but the young actor handles it with with an assuredness that belies his youth and gives the story on-screen credibility. A recommended film.
