Caustizer: I've seen the first three Bionicle movies, but I can't say anything about the latest one, The Legend Reborn, since I haven't seen it yet. The first one, Bionicle: Mask of Light, was my favorite of those first three movies. It featured some of my favorite characters and, being the first Boinicle movie, featured them in a way never seen before (like Takua as you can see in my avatar). The other two, Bionicle 2: Legends of Metru Nui, Bionicle 3: Web of Shadows, were also good, but they weren't great.
jedi472: Here's a list of the years of the Bionicle story in order from my most favorite to my least favorite:
2001 (Arrival of the Toa): What can I say, the first year was simply the best. It was great learning about what life was like in the villages of Mata Nui and who all the major characters were. I also enjoyed playing the Mata Nui Online Game (which I currently have downloaded onto my computer).
2009 (Bara Magna): Like 2001, this year offered a whole new beginning to the story. Also, I'm expecting the movie for this year to be great.
2006 (Voya Nui): The villains of this year, the Piraka, were some of the greatest (not to mention the most spoofed). Also, seeing some favorite Matoran turn into Toa, the Toa Inika, was another great part. Also, my favorite Bionicle game, Bionicle Heroes, was released in this year.
2003 (Mask of Light): The main reason this year is so high on this list is because this was the year in which the first Bionicle movie, Mask of Light, was released.
2008: (Karda Nui and the Final Battle): The climax is often a great part of the story, and Bionicle is no different. What made this year so great was it's shocking ending (I honestly didn't see it coming).
2007 (Mahri Nui): This year feature the Toa Mahri, who had been the Toa Inika before being transformed by the Mask of Life. This year also had a shocking ending I didn't see coming. However, as the Bionicle writer had said, it was "mild compared to" how 2008 ended.
2002 (Bohrok and Bohrok-Kal): Aside from seeing some favorite characters, there wasn't much in this year that was so interesting.
2004 (Metru Nui): I don't know why I put this year so low on this list. It seemed interesting to learn what life was like in the different parts of the city and there was a new group of Toa. I think what made me not like this year so much was because, since it takes place before the previous years, it was obvious that the Toa Metru would succeed in their mission.
2005 (Web of Shadows): Why is this my least favorite of all the years of Bionicle? For the same reasons 2004 is so low on this list. Plus, I felt that the lack of Matoran for any role at all in this year was another negative. Also, the Toa Hordika, who were transformed from the Toa Metru, actually didn't seem that great in my opinion, for some reason.
