Brotherhood of the Wolf *spoilers*
I got this movie about ten years ago from my best friend. He brought it over to the house to watch after we worked on short stories. Since then, Brotherhood has been one of those movies I have to watch every couple years to remind me of how a good story should be told in acts. It's because of this movie that I am always pushing myself to tell stories that reach a deep, psychological yearning for the fantastic that seems to be missing these days.
Sure, we have movies like Avatar, which again, tells a story in acts with very specific transitional necessities, and the story is simple enough to follow. Brotherhood of the Wolf reminds me more of Dracula or Frankenstein, as Fronsac and Mani are hunting a prototypical monster that turns out to be a hybrid of two or three monsters - much like a griffin in ancient mythology. Combine this with the political corruption and religious dogma of the time, and you have yourself a modern-day cult classic.
Oh, and let's not forget the classic examples of Greek tragedy, romance, and taboo subjects, More movies of the last decade could learn from this turn-of-the-century gem!
