I think it is a good moshol. As far as nightmares go, I know that there is much worse stuff that kids in other communities are shown that is way worse. Think of what movies parents bring their children to and what goes on there, both violence and tznius (loshon nekiah)or unfettered and unfiltered internet access. Much much worse as far as nightmares go. And those have no redeeming features at all.
