That's what these threads usually turn out to be. The guys who swear by these shows telling the guys who could care less that they need to watch honey boo boo or some such nonsense and the guys who don't like these shows telling those who do to grow a brain or some such nonsense.
It all comes down to personal preference, really. I don't watch the shows about cars simply because I've been a professional wrench for almost 25 years. Spend 8-12 hours a day in a garage, 5, 6, 7 days a week and I could care less about coming home and watching a tv show about someone else in a garage. Kinda like the fact I have a friend who's a professional chef. He doesn't come home and watch the Food Network. Trust me, over the years, I've cultivated a lot of interests beyond cars.
But that's me. Others have other reasons. All are valid, simply because it's all a personal preference, good for your life, your interests, and invalid for others' lives and others' interests. On both sides of the never ending finger pointing of who needs to do what.
