FilmApe’s review published on Letterboxd:
Jonathan Glazer's second film Birth could easily be dismissed as being overly ambiguous and unesscarily vague. In order to avoid dismissing this film as such, I think taking in mind a quote from one of my favourite high school teacher is benificial. Whenever said high school teacher didn't know the answer to a question (or didn't feel an answer was nesscary) he would point to quote above the whiteboard that read "enjoy the mystery". It is this reason, the mysteries contained in the film, all the unanswered questions, that make Birth such a memorable experience. Well the mysteries, and the fact that Birth showcases mastery of the cinematic craft in every possible area.
Birth is not out to answer any big questions. Yes it explores such topics as eternal love, life after death, and reincarnation, but it is never preaching to the audience. Simply explained, Birth shows what would happen if a decade after a husband deaths, a ten year old boy showed up at the house of the man's wife claiming to be her dead husband. The film explores all aspects of this scenario, but don't expect any answers, because your not going to get them, and honestly, with a film that looks and sounds this good, who cares about answers.
If your not onboard with the film by the end of the opening scene, there has got to be something seriously wrong with you. The gorgeous tracking shot of a man running, combined with one of the greatest scores ever composed, is a one, two punch that I was not prepared for. After this opening, the film could have done whatever it wanted, as I was one hundred percent on board.
In the end the only thing I have to say is I wish I had seen this movie sooner.
