Well that's to be expected. I still remember the school year after ROTJ more people were talking about stuff like Christine, Cujo, Dead Zone and all that than Star Wars. It's always "cooler" to talk about the hard core stuff when you're a kid.
Yeah, because kids desperately want to be "adults"... even though they have no idea what that means.
And adults desperately want to be kids again... even though they forget exactly what that means.
