Clint Mansell makes this movie a masterpiece. No doubt, Darren Aronofsky is an excellent director, and he crafts an epic tale here, but it is the score to this film that captured my heart and rocked my world. It is so moving, so powerful and fits so perfectly with the tone of the film. Synthesis I guess, is what I'm getting at. The plot itself is a little hokey and some of the symbolism is a bit obvious (tree of life, garden of eden etc...) I still think this is Aronofsky's best and most underrated film. Give it a shot, even for the score alone.
