As a kid i used to watch these series but i was so little i barely remember. But all i can remember was that it really used to scare me as a kid. Some say that its very educational, they may be right. For preschool children, it may be. But as I grew up and watched the series again, i somehow remembered that i used to get really scared of their normal behaviours. The show has that creepy silence moments and weird voices which may be really disturbing for the few. I get really disturbed when i see this show on TV. I think that the show has some kind of underlying messages but i could not figure out what yet.
