That mask looks like they ran out of ideas and ripped off Sauron.
I'm now interested, but I'm climbing aboard the 'meh' train. It's got pretty good lodgings, but you get your money back if the train doesn't reach its destination. Plus, if you're not happy with the destination, it'll take you to a new one. Plus it's really easy to get off, given the slow speed it goes.

But I am interested. Not so much in the plot, but more in the quality of the sets. Last time I checked, Pereki and I were sharing a cabin, so I'll talk to him about it. The first sets had more of an emphasis on Technic: they had TECHNIC on the instructions! But when was the last time you saw gears in a Bionicle set? The last ones were (in NZD) a dollar per piece!* And the Muaka is my favourite. I still don't understand how it works. And the Manas... despite one motor playing up with rechargeable batteries they were the pinnacle of Bionicle. Ok, that's an overestimate, but SOMETHING has to be the pinnacle, no matter how low it is . But they just went to ball joints and things went downhill from Mahri Nui.... (at least Voya Nui had Kardas... +5 SET DESIGN)
TL;DR Lego, please add more Technic stuff into it.
*Gresh = 21 parts = 20 dollars = ~0.952 $ / piece
