That may be true, but for kids. BIONICLE felt like a never ending movie, and I loved it .
Yes it was complex, but it kept you hanging, waiting to know what would happen next.
Of course Hero Factory is aimed at kids, not adults.
I thought they would not discontinue such a great line, but they did.
Anyway, I think Hero Factory will sell well. It was a good decision for LEGO, but not for BIONICLE lovers.
