Which ones? There are movies in there that kids can see, yes, but most of that list are either movies from the majority of our childhoods, or movies that kids should not be seeing (not including Harry Potter, but I know alot of adults that enjoy the HP series).

Besides that, I'm not sure what theater you go to, but around here the vast majority of people going to the movies are pre-teens, teenieboppers, and teens. There are not that many adults until the later shows. I RARELY even go to the theater because of this, and if I do, it's usually the last showing of the day.
