In the list of films I didn't like as much on first viewing but grew on me as I aged + watched more times: A.I. (Artificial Intelligence). It was pretty common for this film to be misunderstood upon release, in terms of the story's aims, the identity of the creatures at the end (no, they are NOT aliens although unfortunately they look like aliens from some of Spielberg's earlier works -- they are evolved mecha and the last remnant of humanity that survives), and the influence of each director on the film.
The whole crux of the story is summarized in the initial opening ("What responsibility do human beings have towards mecha, if we imprint them upon us and thus make them vulnerable while not promising anything in return?" It's an ethical dilemma), as the protagonist is basically imprinted onto a mother that cannot commit to being his mother, yet his whole purpose of being is to be a child who yearns for a mother's love.
The whole point of David's journey is to transcend the prior limitations of mecha and bridge the gap to humans -- doing things of their own volition and inner drive, rather than because they were programmed... at least to the degree of humans. David does things in the film once imprinted on Monica that fly against what might have been expected from his programming, it seems to transcend a mere mother-bond instinct. It is like the epic hero's journey just shown through the eyes of a mecha boy. EVEN WHEN HE FINDS OUT HIS JOURNEY IS IMPOSSIBLE (the terrible revelations after he reaches Professor Hobby), he can't and/or won't quit. Personally, I love the ending in this regard, because it's so bittersweet -- the best that can be done, and yet for him it is perfect because it is everything he ever wanted.
The camera framing, odd imagery (like David originally reflected in various surfaces or through non-uniform windows to look inhuman), production design, costume design, is just amazing. The blue fairy statue is perfect. Acting is stellar. Jude Law just moves so perfectly in this film -- graceful while remaining mechanical in its perfection. I'm still kind of in awe of it. This is one of John Williams' most unique scores that I can recall.
I was triggered to watch it after seeing Incendies, because the emotional palette felt similar to me. the special voice cast (Angel, Williams, Streep, Kingsley) are just so perectly cast, and the Dr. Know section left me in tears when he issues his final answer about the Blue Fairy because Williams' voice totally changes to something remarkable, and it's hard in conjunction with losing him so early in life. Kingsley is especially good as the bookend voice of the Specialist as well. There are horrific moments in the film (Monica and David in the woods, the Flesh fair), and then just beautiful moments of longing and loss and unmet desire, or even just the transcendent moments when David refuse to stop because his desire is so strong that it doesn't matter what makes sense or what constraints are placed on him, he refuses to quit in his journey - even his momentary fling with suicidal depression is a human response to unmet longings.
I dunno. I am glad people have revisted their initial impressions of this film over the last twenty years. It is also in the middle golden period for Spielberg (1998-2005 or so) where all or almost all of his films were just so stellar. I'm kind of indifferent to many of films after that (until the Fabelmans).
