Reddit reviews Bionicle: Mask of Light

Yep! From what little I've been exposed to, it's pretty great. To a point. At the very least, I'll recommend the first movie. There's a few cheesy dialogue deliveries and painfully obvious twists thrown in here or there, and the animation quality may not have aged well in places, but it's still a pretty great watch that's held up for the most part, especially if you were a fan in youth. A fun film.

Pretty sure you can find the full movie on Youtube. Enjoy!
