Across the Universe. Simply brilliant, but then again I'm a major fan of The Beatles so I may be just a little biased. Watched it with my dad, and we both had different responses. He said my generation being fed the '60s like a commercial product, which I don't really disagree with; however, his big question was this: what is my generation's cause? I don't really think we have one; and, if we do, it's to not have a cause.
My response was to wonder how many people who protested Vietnam had a personal stake in the matter and only really cared because of that, rather than for the sake of the other thousands shipped out.
