This is a film about romance - deep romance - and it has stayed with me since I first saw it many years ago. There is nothing at all tasteless in the depiction of the relationship between Ashley Sinclair (Richard Burton) and Sara (Tatum O' Neal). It has a lot of purity - partly, I suppose because their love was unconsummated physically - yet, it really was infinitely consummated mentally and emotionally in a way. Two people in love doing, one supposes, the "right" thing - the ending of this film is very heart-wrenching for anyone who has ever had to make difficult choices in love. I thought that both Richard Burton and Tatum O'Neal were perfect in their roles, and their love was highly believable. I also thought the title song was very memorable - there have been many times I have heard it in my head over the years. A great love story, that, unfortunately, not that many people know about.
