I'm not sure which part of the sentence you're contradicting...
If it's the part about Agori: if you put a Glatorian in there it'd look rediculous.
If it's he part about Mata Feet: the connection is pins like on Ignika's Skyboard, which Mata feet can't go on.
Well, even some CGI pics have impossible poses(I think Toa Ignika had one once). But I think they do the poses like to try and get a living feeling out of the characters, If they only had 13 points of articulation moviewise it'd look unnatural.
The movie does sound(and seem) Bleh. But it's Lego and Tinsletown(who I've never heard of, not that i'm an expert or anything). It's not a high budget thing, probably just to give fans interest. Bionicle Adventure 10 is the best selling Bionicle book, which came out after the 3rd movie, so maybe Lego is trying to stimulate purchase of sets.
I agree with you on the first point, but I think if the characters were limited by setwise posing it would lok odd and stiff. And there's always an ugly person in movies
