Promotional material was garbage, and the story sucked, yeah. My main issues from the sets, I suppose, don't necessarily come from a design perspective but rather the theme as a whole and the "innovations" it brought, namely the Hero visors and the Villain heads. The visors for the Hero helmets, while a nice idea, made the heroes' heads extremely tall and awkward looking in some cases (although not always). The brains were just terrible all the way around; all the cool, creatively designed villain faces were ruined as far as MoCing goes due to their need to attach to the stupid new head piece+brain in order to look remotely good (this was due to the flat nature of the villain faces).
Overall, though, I did really enjoy some of the sets from the wave. I am a fan of the villains for the theme, despite the stupid brains. I think they all look good to a degree (except maybe Aquagon), and they did their job fairly well. The heroes, though, I was far more mixed towards, and don't even get me started on Jet Rocka.
