the audience applauded

A lot of perfectly good film show their cards early, establish a unique premise and let the audience explore a topic at a leisurely pace, without much in terms of surprise. this film is not one of those films.

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

The film's masterful storytelling did its job. The message was clear. No need to overdo.
