Conclusion: Criterion collectors will surely be picking this one up. It's one of the more recognizable films in the Criterion collection given its source material. Brooks does an admirable job trying to encapsulate Golding's richly conceived parable. Criterion has done a great job restoring the video and audio to high-def standards. It's a must-own for collectors, that's true. For everyone else it's certainly recommended.
Conclusion: Peter Brook's film remains the best adaptation of William Golding's famous novel. But if you are unfamiliar with it, I strongly encourage you to read it first before seeing the film. In my opinion, the novel is substantially better and far more thought-provoking than the film. Using a new transfer from a 4K digital restoration, Criterion's Blu-ray release of Lord of the Flies is likely to remain the film's definitive home video release for years to come. RECOMMENDED.
