This is hard. Mask of Light was the shining moment of my Bionicle fandom. I watched it the day it came out and loved the movie. 8 years later it's not really a great movie but it has sentimental value for me. Takanuva vs Makuta was quite lame and it lacked good action but I used to love it. However Legends of Metru Nui was good when I first saw it and when I jsut recently saw it. I went with MOL though since I used to love it.
