I had high expectations for this film and it utterly delivered on them all, I held my emotions together until the very end when they got too much (watch it, you will understand). I am now dealing with a massive man-crush on Ryan Gosling - I almost watched the song scene twice.
At under two hours I was worried it would go by too quickly and the story would not have the substance I wanted -- none of my fears ever came true, I loved it from start to finish and I want to buy it on DVD.
