Whilst I can agree with Keith on it always being overly serious, I think it was an interesting choice for a children's show. Personally, I would have liked to have seen it aimed at teenagers instead, but that might have done even worse.
I think the marketing for the show was overall very poor, and - let's be honest here - being on CW4Kids was basically a death sentence for the show. They definitely got away with some things later on that 4Kids would not normally allow, but that still held back the show far more than I would have liked. I think the broadcaster WAS the biggest problem, albeit not the only problem.
Whilst I loved the show AND loved the fact that they used the name "Kamen Rider", I think it would have been nice if they at least explained the origin of the word "Kamen" (even if they made some crap up. It may be Japanese for "masked", but they could have pretended it was "Ventaran language" or something) so that children would be less confused. Then again, how necessary that is, I'm not sure, because whilst "Kamen" DOES mean something, it's not really vital to the show to know the translation of the word.
There are definitely some plot points that could have been handled a little better, but I think that it was overall a good show. Also Camo/Verde had actual screen time!
Overall, I like the show, and I still maintain that it's better than Power Rangers in general. I guess it doesn't help that everyone and their mother thought that Dragon Knight was a Power Rangers rip-off (and they totally missed their chance to say "Kamen Rider was a thing before Power Rangers or it's Japanese counterpart, Super Sentai", in a less cumbersome way, of course), but I think it's a shame that we won't be seeing any new Kamen Rider adaptions any time soon, because I think they could do a great job, especially if they got away from 4Kids. I mean, 4Kids flat-out refused to air the last two episodes and made them available on their website to US residents, which meant people had to rip them from the website just so we foreigners could watch the finale!
One thing we can all agree on, though, is that Kamen Rider Dragon Knight is much better than Masked Rider.
Actually now that I think about this, couldn't they have named it something different or would Toei have required it to be part of the Rider brand?
Maybe they didn't want to link it to Masked Rider, but could they have simply named it 'Dragon Knight' or something?
I believe Saban (or perhaps Disney at the time - I don't know if it was a property that changed hands alongside Power Rangers or not) still owned the rights to Masked Rider, so they couldn't have done much about it, but I believe Steve and co. did also want to distance it from that.... abomination. I'm sure Toei did probably want it to be part of the Rider brand, knowing Toei.
