I did liked a few of the alternate dimensions, though. I'm actually not too far set against them as other people were, as I find it interesting how different they are from one another. And I also ironically enjoyed 2006 as well, even though the entire year was advertised with rock bands, chain fences, and other "modern" things.
A lot of the 2006 promotions were ridiculous, but I too liked that year. Part of it was that we finally had a team of villains that truly complemented the Toa. Even the Bohrok Kal, the only sentient team of six villains we had seen up to then, had largely identical personalities. 2006 was the start of a shift toward more characterization for villain characters, which climaxed in 2008 with the Phantoka and Mistika Makuta. It's part of why I have the somewhat unpopular opinion that Greg's writing actually improved as time went on, at least until he was left to forge ahead on his own after the theme ended. Many seem to dislike the later years of BIONICLE, and I'll admit the story serials always rubbed me the wrong way, but I think the story improved each year until the theme had to be cut short, and I do think that Greg played a big part in that improvement.
