I got into this show from a very young age. It was the first TV programme I ever saw religiously, so it meant everything for me. In a way, it made me discover many things about life that I didn't know at the time. You never fully understand the adult themes they show us here when you're a kid, but you never feel completely unrelated to them, either. They appeal to you because most of the time these topics are things that were glued into the world even before you were born.
I have to admit that the first time I got hooked into QL was because I loved seeing Sam leap, that was all. I was about 12 and didn't care much for the story except for the time when he fixed it at the end and he was surrounded by the blue elecric light. Then I grew up a bit more and began to pay attention to the stories themselves and what they meant. They carried a strong essence and a strong message during my adolescence. I remember that there was a time, probably during my highschool years, when I used to read too much into the show and even wanted to become Sam at some point because I saw many wrong things in the world that most of the time didn't get "put right." I fantasized about it and it meant the world to me. But many, many years ago I grew out of it. Got other ideas, other concepts in my life, other experiences, and now I can't help to view most of these worlds where Sam leaps as a bit two-dimensional. That doesn't mean I don't like it anymore. I still love it and I won't ever stop being a fan, that's a fact, but now it just means great entertainment to me, nothing more. If I ever have kids, I'll show it to them, that's for sure.
One thing I noticed the last time I saw all the episodes again was that I loved more Al than Sam. Probably because, even if he is only the Observer, he's clearly a more experienced and mature character, in my opinion.
