I watch it because I drive/drove race cars. I love auto-racing. I love the noise, the personalities, and most importantly the cars.
I can't answer your question, really. If there isn't any draw to watch it, you probably just don't enjoy it. No shame in that.
I don't really understand why people watch football/basketball/soccer; but I understand why I don't get it -- I have no interest in the sports.
My father watches the Tour de France every year. He was an extremely in-depth established cyclist for years and years.
When I watch the Tour with him, I fall asleep. He falls asleep if I put him through auto-racing.
I think it's the same kind of thing.
If it's any consolation : your problem is a widespread one. The FIA is trying to make it more spectator-interesting next year by establishing a big wall of rule changes.
