Don't spend too much time on what was at the moment not meant for adults, like there is alot of other art to look at and interpret. It was more of a don't get crazy into it, my own Dad got super weird into interpreting things he thought he found in Doctor Who. It was both sad and weird. Just maybe don't dwell to much on things people didn't also give much thought to.
Not crazy into it, just generally appreciative of media with internally-consistent science or magic.
