They may be part of your culture but they will never be part of mine. I retire next week so as you will gather I'm totally the wrong age demographic.
I could sit and watch BBC 4 documentaries from morning until night. I like television that informs and educates me. I'm not much interested in a load of American make believe.
I get that younger people don't understand the slapstick of Mrs Browns Boys and maybe Two Doors Down. Again it's comedy from a different era, but having said that it's very very popular.
Personally I think American imports ruin television but that's my personal opinion. The good ones are few and far between. At the end of the day if we all liked the same things the world would be a very dull place.
One of my smartest moves however was the day I got rid of Sky - I have never regretted it for one minute and neither has my wallet.
