I actually didn't like Al when I first watched QL. (Can you believe it?) ... Yep, his attitude about women really rubbed me the wrong way. ... Altogether it took about 2 weeks for Dean Stockwell to charm my socks off. Al has so many sides that he seems like a real person to me. He still has a dark side. But he's amazing.
I had a similar experience. I watched the episodes in order (on hulu) starting at the beggining, and when Al first showed up in the pilot I did not like him
at all. He just struck me as a selfish, perverted, rich guy type (the car and way he was dressed gave me this third impression) who only cared about himself and always had an ulterior motive. In fact, my first impression of him was so bad that when he told Gooshie that interfering with Sam leaping would kill him, what I thought was, yeah, I bet you don't actually care about this Sam guy, I bet you just don't want to have to fill out the paperwork.
Boy, was I ever wrong. Even by the end of the first episode I knew I'd been dead wrong about that.
Over the course of the rest of the season and some of the next he slowly but surely began to win me over, initially against my will. At first, I couldn't for the life of me understand why I even liked the guy, let alone spent every episode wishing he'd hurry up and show up and feeling dissapointed when he left. I kept telling myself
Sam should be my favourite character. Sam's the nice, sweet, sensitive one, I said to myself. Sam's the respectful one. Sam's the young, classically handsome one. I normally hate guys like Al, so
why do I love this character so much?
I think I've pretty much figured it out now. Al's the more compelling character (to me), because he's more complex; you don't have to dig as much with Sam, so it's not as powerful when he acts sweet and caring, but with Al the contrast makes it all the more poignant. Al's a perverted, womanizing creep, there's no way around that, but underneath all that he's also a guy who really does care about people, women included, and no matter how much he mistreats them, I don't think he really means to or wants to hurt them.
I think the other reason Al quickly became my favourite character over Sam is that he's so wierd and quirky, whereas Sam's more normal (despite being a super genius and uncommonly selfless). Oddballs generally appeal to me more than characters who are designed so that everybody can relate to them. I think that's also why my feelings about Al are so different from my feelings about most sex-obsessed, womanizing, inuendo-happy characters. Most of them are suave, stuck-up, alpha-male types, whereas Al was always this weird little guy with a crazy, eccentric taste in clothing.
