I know that this is a Spanish original, and I LOVED IT! But since I own Vanilla Sky, and it had such a profound affect on me at that time in my life, I can't help but be more drawn to that version. It wasn't well received when it came out, but I got it immediately. The metaphor, the twists were all appreciated by this SCIFI lover. -I for one think both films should be hailed for imaginative film making. And BIG UPS to the people who conceived it!
