Ben believes that he has the power to change people's lives for the better. He acts like a mysterious angel, trying to decide who he is going to bless and who he is going to judge. Does any of us have the right to do that? Should we make decisions like that? Should these decisions be made completely impartially? What happens if you fall in love with someone you are trying to judge? Your opinion may change by the end of the film.
One aspect of the film that stuck out to me visually is the jellyfish. Early in the film we hear of Ben's childhood, and how he was told that the box jellyfish was the most dangerous animal in the world. Yet its beauty is astounding. The juxtaposition of the two drives the meaning of the film.
Seven Pounds was a beautiful story of....well, I don't want to ruin it. It makes it hard to write a review on a film whose meaning is completely tied up in the suprise ending. Let's just say that it was very enjoyable, beautifully done, and emotionally powerful without being cheesy.
