I can't imagine keeping him away from the great satire of the early Simpsons, Monty Python, Yes Minister, and Fawlty Towers. Ditto for favourite movies.
Your children will want to decide for themselves what is worth watching and will resist too much parental interference. My kids think "Call Me Maybe" and "Gangnam Style" are great songs. In the car they listen to Crosby Stills, and Nash and like it.
Maybe so, but that statement could be true of anything, TV or otherwise. (I suppose that's my punishment for having terrible taste in music as a teen!) As I see it, we are responsible for editing the choices available to our children in an age-appropriate way that respects their individuality. Then they are free to make good choices.
Incidentally, it was my father who introduced me to Gagnam Style! That tells you what kind of pop culture maven I am.
