Yup - I despise the notion that smoking makes ANYBODY look cool.
Humour. It is a difficult concept.

That said:
Of course it is. It's also a very successful one, and I think it'd be fair to say what is and is not cool is frequently dictated by marketing.It was a marketing ploy
Nobody smoked in LA Confidential - a movie set in an era when everybody smoked and it didn't harm the movie's story in any way.
It's an awkward call that was probably there just because people would complain about smoking - America is very tetchy on the subject, I understand, but I definitely draw the line there. You know they thought about having Gandalf not smoke in Fellowship of the Ring? I think even gum was suggested instead. Imagine that!
It needn't have featured so many alcoholics or divorced people and so on. Happy happy gumdrops.Battlestar Galactica needn't have featured any smokers then people wouldn't have had to worry about going cold turkey.
