2001 - 2003 would've been better if the Toa could turn their heads and hold their arms up. 2003 would've been better if the Bohrok-Kal flash animations were more fleshed out, and if the Kal sets had more new elements to distinguish themselves from the Bohrok. 2004 would've been better if the Toa Metru had more unique builds, and could hold their arms up. 2005 would've been better if there were more heroic-looking sets (back then I was the type of kid who predominantly bought the good guys, and the majority looked like monsters; I actually lost interest in Bionicle for over a year). 2006 would've been better if the Inika had more unique builds, and had traditional heads and masks. 2007 would've been better if the lime green limbs weren't so brittle. 2008 would've been better if the Phantoka and Mistika Toa actually looked like the characters they were supposed to be. 2009 would've been better if the disassociation of element and gender was used to have more female characters instead of less. 2010 would've been better if the line wasn't cancelled prematurely (If I remember correctly, Greg Farshtey had a story outlined for a few more years), or at least if we got full-sized sets or a movie (it would've been epic); AND if new story serials weren't started just to be abandoned. I could go on, but it just gets me down thinking about it. 2015 would've been better if there were mask packs (I could say the same for any year after 2003 really, but 2015's nostalgia factor just demands it), if Gali's and especially Lewa's masks were more faithful to the originals, if the concept of non-elemental mask powers was retained, if the protectors and villagers had unique identities, if the story animations had more depth (unless they're planning for another medium to serve that purpose), and if the line was launched more ceremoniously. At least it's not over yet.
