Where are people getting these statistics? The only time I remember confirmation of such a fact was back in 2002, which was a time in LEGO's history where most other themes were suffering (even the town theme, which is part of why it was replaced, first by World City and then by the City theme we've had since 2005). It certainly wasn't LEGO's best selling brand at the time they ended it, and probably wasn't for a few years before that. Let's face it; Bionicle did not keep itself going as strong as it did near the beginning for its entire run, or they never would've ended it. Perhaps Hero Factory hasn't had such resounding success as Bionicle did in its heyday, but I hardly see that as a reason for LEGO to bring back a failed theme in its place.I'm just assuming that it takes a very special place in the hearts of many....It does, but keep in mind that those "many" weren't enough to keep the theme alive past 2010 in the first place.Actually, Bionicle was abandoned by TLG because of the overly complex story. Not because it was losing popularity or because it was mediocre.Yea, I highly doubt that.If Bionicle was still popular and selling well then it would have not been canceled.The story was complex to a degree, but how many fans actually followed it outside of the comics?
