Kamen Rider Ryuki is a fun watch. I wouldn't necessarily call it perfect - the moments of levity feel a lot like Agito before it, which is a series I do not particularly like. I found, especially early on, the moments of the characters interacting with each other were kind of making me feel secondhand embarrassment rather than humor over the situation. I'm also not big on the suit designs in this series, especially the main character's. However, Ryuki is still a very good story when analyzed as a whole. Interesting concepts and characters, a solid character-driven story, a neat gimmick in the belts and transformations of the series. It's a series I have a lot of respect towards and one that I can look back on fondly, but can also recall the many times throughout the series that I found myself sort of let down by the ways characters interacted being a bit annoying. It's not perfect, but it is definitely a huge step up compared to the story before it in the early Heisei catalogue.
