These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Kamen Rider Hibiki
Awesome Music: For a series that has weaponized sound and musical instruments, it is to be expected to have a lot. Kagayaki, the 1º opening, takes the cake.
Broken Base: The second half of the series. The general consensus seems to be that those who liked the mold-breaking approach of the first half disliked the second, but those who prefered the franchise's more traditional style prefers the second half over the first.
