I can identify with some characters in some situations, but as a whole, Dallas is pretty different from real life, and that's a good thing as
@Toni said.. I can think how I'd probably feel if I were Bobby and Mark was trying to take my wife from me. It's not exactly identifying with him, because I don't think and act like Bobby, I also know that if I did some of the things Bobby does I'd wind up in legal trouble quickly. So I just think "if I were Bobby, this is what I'd do" in accordance with how things work in the world of Dallas. I know he can get in fights and not have legal problems as a result.
I find JR very entertaining but I don't want to be like him. Why is he married to Sue Ellen if he can't love her and be faithful to her? I'd rather be like Jock than JR or Bobby, if I were going to choose one person from Dallas to be. I'd want to be the man who founded his own company, built it from the ground up into a huge, successful company. The man married to the same woman for over 40 years. He knows what he wants in life and goes after it, while a lot of others around him seem confused as to what it is they want.
There is a real lack of characters on TV dramas today like Jock Ewing. Maybe I'm just watching the wrong shows, but except for Yellowstone, I don't see any characters at all similar to Jock. The men in TV today, for the most part, seem less masculine.. They're more fragile. I really don't know who these fragile, less masculine types of male characters are supposed to appeal to or why they would appeal to anyone. I like how Jock says what he means and means what he says. His handshake is better than a contract. Is the reason they have these more fragile, overly sensitive, less ambitious, highly dysfunctional male characters on TV today who just aren't too tough is that a Jock Ewing character today would frighten the millennials?
