Kevin Spacey is unbelievable in this. Though coming from a teenager, I'm sure it sounds odd but I can relate so much to Lester Burnham in American Beauty, I don't know 100% why, but this quote sums it up perfectly:
"I'm not exactly sure what it is, but I know I didn't always feel this…sedated"
also! The soundtrack for American Beauty (done by the genius Thomas Newman) is too stunning to put into words!
