now, i must say, i disagree. in my own opinion the mistika were alright sets. the phantoka might just be my favorite set wave in the whole of bionicle.
i know, gali's mask looks odd, and kopaka's lens is on the wrong side, but i'd have these designs over the nuva/mata designs any day.
the nuva/mata are liked by most because of how iconic they were. but they cannot really be posed well, their arms flop down when you put them up,
their parts are difficult to use,(aside from masks and weapons) their heads cannot turn,
at least not without modifications.
the phantoka/mistika on the other hand, can pull off a variety of poses, they can actually hold their arms up, they have more useful parts for mocs,
etc, etc, etc.
i think they are good representations of these characters.
you can disagree with this, if you want to.
but i think the phantoka/mistika get far more hate than they deserve.
