That's more like it.
My family's experience with BIONICLE went something along these lines. My family can be a little concerned about spiritual stuff, and there was a whole list of themes that they didn't particularly like the premises of, so they didn't allow me to "follow" them. A lot of these they decided to loosen their standards on as I grew older and (presumably) learned the differences between reality and fiction, with the exception of a few themes, which I concur with them are a little creepy/possibly demonic, or found my own reasons to dislike (see: Chima).
I got my first BIONICLE set as a part of the BrickMaster program, and about that time my parents considered the sets alright, but still didn't allow me to follow the story. Some of their decisions were a bit arbitrary, for example they seemed a lot more open to the line in 2009 simply because the visual style was a lot less dark. Even when I got fully invested in the line in 2013, they still didn't like a lot of the visual stuff (which is part of the reason I haven't watched the movies or read most of the comics, alongside general apathy).
Parents' rules are weird. At my age I think I understand the intentions behind them a lot better, though we still don't see eye to eye.
