Anyway, back to the topic at hand; I think Eiji was particularly dull as a character. Plenty of people hate on Gentaro, but I at least felt I knew where the character stood, Eiji felt really wishy-washy to me. Like I can tell hes a good guy but at the same time he doesn't have Gentaro's determination, or Shotaro's sense of justice, it seemed to me that he was a good guy just because and in my opinion, thats rather weak. I realize that OOO was truly Ankh's story, but I don't think that means Eiji had to be so bland. imo he is the most forgettable main Kamen Rider since Wataru.
I've only seen up to episode 10 of Kuuga, and I didn't feel like Godai was an especially memorable character, but that might be due to lack of episodes.
