re-reading or watching something

Its interesting how things seem so much different when you do read or watch it for a second time.  Some TV shows that I watched when I were younger are just completely stupid.  Some of it seems poorly written and too ordinary.  I almost wonder why I even watched the shows in the first place.  On the flip side, sometimes with age things seem to get better.  Some books seem to make sense, and are funny that did not seems so when I read the book at a younger age.  This would probably be because I get the jokes and storyline better with age.
