Joker007

Decade was the first KR show that I had watched, it was so interesting for me that I finished the series within few days, but sadly the series was short & story didn't conclude properly, one have to watch the movies to continue the story, but that makes it more confusing in the sense so many questions still remain unanswered, it was a weird choice, the series could have been done better if it was done well it could have been great like Kaizoku Sentai Gokaiger. Both are anniversary series with a central character/team who can transform into, or use the powers of, past heroes from their respective franchises & feature the main characters journeying through a multiverse of past heroes to achieve a specific goal, and they share the common theme of celebrating previous generations of heroes.
For me Kamen Rider Decade is better than Kamen Rider Zi-O but sadly Zi-O gets proper ending and more episodes than Decade, even without proper ending and other issues Decade is still better than many Heisei Era KR shows that had more episodes but test viewer patience i.e. the start is great then it drags, then around last few episodes things get interesting but for some even the last part is tiring, since I am not a hardcore tokusatsu fan who watch this series like any normal TV series so what I like may not be same for the fans of the series etc.
