So by this logic I don't think Kiva should be considered a Kamen Rider series because it was to heavy on the romance and the actor for Otoya had to much fun playing him. And how do you know being in the Imagin suits all day are fun. It must of been hot as hell in those thing and Seiji had to learn the mannerisms for Ura, Kin, and Ryu for when Den-O was in there forms. If anything Den-O was Seiji hardest Rider. Not to mention it must not be pretty fun when you have next to ZERO vision.
I'm really sick of people hating on Den-O because it's funny. It was a comedy! They were trying something new! Just like how Kiva was a romance. Not ever Kamen Rider has to be the same. We except Hibiki because he "wasn't really a Rider" but we don't except Den-O why? Because he had the belt? Because he said "Henshin"? Because he had a kick? Because he has bug eyes? Oh no it's because he TRIED TO MAKE LITTLE JAPANESE KIDS LAUGH!!! No one has to like Den-O and you can hate it for all the movies it has that's understandable but Den-O is a mother fucking Kamen Rider.
