Slightly spoilery:
I binged the whole show and then the movies. The show is a little campy and ridiculous sometimes, but the longer it goes on the more serious it gets and the higher the stakes. The fact that we gain some allies even from enemies, the fact that Banjou and Sento will literally risk/choose death if it means saving the other, and the sweet moments between the team are all wonderful. There are good speeches, some lovely ideals, and a lot of fun combinations with the Kamen Rider Build suits. I've watched a good amount of episodes multiple times. Sometimes I see the actors in other shows and have to come back to KRB because it makes me nostalgic.
