My DD, 15, and I watch Gilmore Girls and then Smallville, sigh we both love Clark Kent's smile and beautiful eyes. We both watch 7th Heaven on Mondays and I have started to get her hooked on Dead Zone and Monk.
We have watched TV with each other for a few years now, it may sound corny but I like that closeness and they are all good clean shows. She got me hooked on Gilmore Girls and Smallville, we use to watch Buffy together but she liked GG better and last year I stopped watching Buffy too.
