Lord touch me, I hear that you're a fan of kamen rider, any shows in particular? Do you prefer Heisei or Showa era?
If you have seen Kamen Rider Taisen featuring Super Sentai, you would know that both are excellent! Personally, I tend to favor anything Heisei, even “neo-heisei”.
Agito is my #1 favorite and has the best set of riders. Somewhere near the top is also Ryuki, which receives a lot of hate– but its darker tone and abundance of riders is what makes it interesting. Agito and W are my suggestions for anyone interested in getting into the show.
No matter which you pick, the most important thing is that major justice is laid down for all (and it always is)!
