He looks better with hair, yes. But doesn't everyone when they have good coverage?
No, the point was, he doesn't look better with hair.
Actually, with hair, he only just looked like every other actor from that era... nothing particularly special.
That's entirely right. As a sly guy he had a special quality that no one else was able or perhaps willing to match for years. Then I believe Kojak, Telly Savalas, used it with tremendous success in his TV series, followed by other celebs, such as Bruce Willis who seemed most natural when he embraced his genetic trait, and others. But, truthfully, in the US at least, Yul put it out there and others followed. He looked good bald, distinctive and very with it.
