Just as Victor Hugo's novel is considered one of the most important books of all time, this movie may be one of the most important films of the of the 21st century. If you're expecting the musical - forget it - it's not. It's dirty and gritty and honest.
There is no satisfying ending to the movie. The outcome of a single, individual story is not important. Published in 1862, Victor Hugo wrote in his preface: "So long as there shall exist, by reason of law and custom, a social condemnation, which, in the face of civilization, artificially creates hells on earth ... so long as ignorance and misery remain on earth, books like this cannot be useless." It's 2023. Nothing has really changed in 200 years.
The story here is great, and relevant. The film is fabulously well-made.
