Well, sentiment was in fashion then. It's out of fashion now, but I still dig it.
As much as I feel silly quoting an ad for Sky TV, there was a series of adverts featuring interview snippets with film stars talking about their favourite movie moments and thoughts on film. One that stuck with me was Anthony Hopkins stating that he enjoyed sentimental movies. I think he put it like, "People say that sentimental movies are sappy, but you know life is sentimental."
I can agree with that and as I've gotten older and more sentimental I've embraced that side of me and I'm not sorry to say I really enjoy some Al Green or Marvin Gaye from time to time. Hell, I think Lionel Richie's "Easy Like Sunday Morning" is great!
