Although there are noticeable differences, the likenesses found between this movie and the book greatly overshadow those. I found the same emotions running through me as when I was reading the story. Great story of politics, action, and love, I highly recommend it, but agree with the PG-13 rating. I have young children and would not want them to see this, but that's my own judgement. The actors really have chemistry and I cannot wait to add this DVD to my arsenal!
