I don't mind, and in fact encourage the site shifting focus.
I do mind when members make a passive-aggressive blog entry, and then lock it so that the targeted members can't even defend themselves. I mean really, who DOES that?
I mean, seriously. My brother and I loved BIONICLE, but we were okay with it ending. We do, however, take offense to people blaming LEGO for what was, in essence, a wise business decision. We don't like when people stereotype people who don't want BIONICLE back as pretentious members who view all those who want BIONICLE back as newbs. I mean, that's just rude.
Not saying that's what all of them think. But members who continue to dwell on the past, and won't consider some of LEGO's newer offerings, bring an overall feeling of negativity to the site.
Overall, members such as these continue to paint the false picture that BIONICLE fans who don't want the theme back are somehow traitors to the cause, and are thwarting their revival efforts. Or that those who don't want the theme back shouldn't voice their opinions why, or critique theme revival proposals that address the wrong issues or don't have a chance of success.
Me? I think BIONICLE had a good run, but LEGO shouldn't dwell in the past. They've continued to make great themes like Ninjago, Alien Conquest, Hero Factory, Atlantis, and more since BIONICLE's end. And they've learned that both themes with lighter stories and those with heavier stories can both be successful. For every theme like Ninjago, Exo-Force, and BIONICLE, there are themes with less complex stories like Power Miners, Space Police, or Hero Factory. And I, for one, am really okay with that.
(I'm going to leave this entry open to comments, so I don't come across as completely hypocritical.)
