I know you might say that it's because of the sales but why the sales were dropping? I know the story was complex but, I think it's that the story was based on the mask of life. The idea was good but it was the same thing each year. It might also be the build. It was the same body build and the same weapons each time! When BIONICLE started, it was a "Mask Hunt" for the Toa and the kids. In 2004, the story was more of "Disk Hunt". Then, it was just the same "Mask of Life Hunt". I think that BIONICLE's ending was supposed to be because of the same purpose of the heroes. What do you think? Reply to this post about your theories!
