You can probably tell a lot about what old actors people prefer. In fact, I'm sure there is a personality test about it online. Example: I hate Clark Gable. He was an excellent actor, but was only able to play a charming alpha rake. He was a douchebag loser in real life and it shows in every frame - you can't trust him, even when he's the good guy. It's in his face and fake teeth. You just know.
Conversely, there is William Powell, who seems to inspire the truest love in everyone, not excluding me. I am often surprised by how many people know who he is, but people really love The Thin Man.
He is urbane and charming, yet the best at understated wry comedy.
