My problem is that I can't be convinced in the classical sense. I'm either interested in something or I'm not. And no matter what people try to convince me that something is good, if I'm not interested I won't watch it. I've had people borrow me stuff to check it out. I politely returned it a few weeks later, claiming I didn't have the time to check it out. Sometimes it's a curse. I guess I am the proverbial donkey.
And then comes the day where I'm bored enough or just stumble over it by accident (e.g. zapping through the channels). And once I'm hooked, I'm committed.
This happened with Mad Men when I stumbled over the pilot episode on zdf_neo in the dead of the night.
