John Beck was one of the few actors of that time that had "what it takes" to star in a supersoap, with his aura of modern Clark Gable (he survived to "Flamingo Road" and got the girl at the end!). About the Wade woman and her unbearable daughter, they deserved every bit of criticism they got, and more. I didn´t watch "Dallas" to see a celebrity who had been married to a rock singer, and couldn´t act at all. I wanted to see actors: Mary Crosby was the daughter of a famous actor, but she did a great job as Kristin, and even became her eventually...
I don´t think that Mark stalked Pam, that´s an opinion from the 19th century if you let me say this. On Soapland, men and women are free to love (and bed) anyone they want. And yes, Mark is a very hated character, I´m sorry to say. He didn´t follow Pam the way April did when she followed Bobby to Vienna. Of course he had designs on her, and you probably know better than me (

). But it was quickly obvious that he didn´t want to have a fling with her, he wanted to marry her, and even waited for a whole year until they went up those upstairs à la "Gone with the Wind" (you see, his similarity with Gable?).
Bobby was castrated by Jenna, and when April found him in Europe, he was a shadow of his former self. Not only he didn´t care at all about what she had done to his family (getting a share of their company just using a technicality), but he also didn´t mind that she bitched around Dallas whenever she saw him with other ladies (which she wasn´t, actually...). Before Bobby, she offered herself to Jeremy, Wes and slept with married man J.R. several times (which she didn´t even admit: she said later that "it was only once"...Liar!). April complicated Nicholas´s life a lot too, and even indirectly caused the death of the detective she had hired.
The writers themselves saw how unattractive April actually was, because Bobby went through one-night stands and relationships with other women until they manipulated the audience by having her beat by that wacko Tommy. Of course I hate any kind of violence, but here Bobby was trying to kill someone who had an addiction (and he knew it) and the writers used the old cliché of Bobby rescuing the "damsel in distress" as a way to get them closer again. That was completely b.s. and the most contrived way to pair two characters up.
And another thing I never understand when it´s mentioned here: they never introduced Mark as Bobby´s friend, but as the client of the best "Dallas" lawyer needed by Miss Ellie. There is even one scene when he hangs up the phone and, when he sees it´s Mark, he says: "Graison? I haven´t seen you in ages" or something like that. It´s not Guzzler or Cantrell who we are talking about here, he´s just one of the many playboys from "Dallas".
Just add that Bobby and JR´s obsession with winning Ewing Oil is a proof of how immature both of them were. They were adults and their dad was dead and buried (well, he was just feeding fishes in that lake, but you know what I mean...) and they were still fighting for who had the biggest...ambition. It made a great season of TV but in reality both should have gone to the shrink. Pam took a lot of crap from the Ewings and that said a lot of how much she loved Bobby (I would have left in the middle of the Pilot miniseries, I can tell you...). Just my 2 cents.
