"Kill Bill." Beautiful, philosophical, and full of action. And all of this is organically woven into one film.
"Sin City." An incredibly beautiful film with a great selection of characters: Mickey Rourke (everyone remembers his Handsome Jack), Bruce Willis (perhaps my favorite actor), Jessica Alba (acting skills weren't required, but her appearance is as if she stepped out of the pages of American comics), and so on.
"The Ring of the Nibelungs." A very subtle work by the screenwriters who brought together several versions of the legend (I know about 5), realistic battle scenes, a successful selection of actors and music, and the absolutely irresistible Brunhilda, played by Kristanna Loken. An example of how to make a saga.
"South Park." The absolute leader in the intellectually entertaining genre. Individual episodes, such as "Make Love, Not Warcraft," can easily be included in the modern school curriculum.
Among adaptations of famous literary works, I would mention 3:
"Cruel Intentions," based on Choderlos de Laclos. A rare case where Hollywood adapted a classic for a modern audience and did it even better than Europeans. An excellent musical selection is an added bonus. We confidently give it a five.
"Pride and Prejudice." Surprisingly, a simple read by Jane Austen was turned into a watchable (although with some difficulty) film, even for a male audience. A solid four for the film, which is already a success given the source material.
"Children of Dune." Simply a breath of fresh air for Herbert's fans after the mediocre new "Dune" and the terrible one by Lynch in 1984.
It may not be entirely canonical, but the spirit and atmosphere are conveyed, and a special respect to Brian Tyler for the wonderful music in the film. A four-and-a-half, because the book is still much better.
