For me? It really was American Beauty (1999). For awhile after seeing it, I savoured every moment of my stupid, little life. I lifted weights. I studied. I listened to cool music and I bought a cool car. And for awhile, with the cool girl who took notice of me and who I eventually married, life was absolute bliss. And then she died because of some drunk fatass who crashed into her car with his truck. He's dead, too. Burning in Hell, I hope. Then I just let everything go. What was the point?

But I don't regret those four years of absolute bliss, at all. Not one bit.
