Yes, but not every point made here is a valid criticism against the overall theme.
Saying it's copying Bionicle is objectively false, and the whole "it's taking up shelf space" thing is a pet peeve at best, since it's not the fault of the theme itself. It's just new and polarizing, like Bionicle was last year.
I'm all for valid critiques and simple preferential differences. I for one think the show's pretty mediocre and that the names, though grounded in reality, take the whole pun thing a bit far. However I think the sets themselves are fine.
