Ah yes, good ol’ 2009 
I remember it well. I got all of the winter wave sets (Glatorian, Agori, Fero and Skirmix, Tuma), and got a few of the Glatorian Legends.
My 2009 Collection:
I was also pretty hyped for the Legend Reborn. I remember watching all of the clips that Lego would release on bionicle.com before the movie’s release, (which altogether combined to be about a third of the actual movie!). I even got it on dvd! (I still have it too…). When I watched it, all of my excitement/hype shattered and was replaced with bitter disappointment…
(Also, Glatorian arena was a pretty good game… yep.)
(Also also, the Skrall shield is the coolest thing evar!!!)
Despite my opinion on The Legend Reborn, I thought 2009 was a pretty great year for the sets (minus agori, eah…). I really liked the whole ‘game mechanic’ health meter thing that they tried. I also liked that the story was set in a new location, and focused on Mata Nui’s journey through Bara Magna
