I watched Gavv. Once I got past the silly looking suits, the story was good. Despite his optimistic attitude, Shouma is not only pragmatic, but calculating when it comes to Granutes (stop taking/making Soylent Green or die).
Gavv Rider trio felt sufficiently respectfully to the Showa era (Ichigo, Nigo, V3). Stomach Inc. were a good change-up of villains and their whole Dark Treats business was predatory and gruesome (for humans and granutes). Bocca was built up to be the final villain of the series, but someone wanted their Dante vs. Vergil finale with Shouma and Lango, so it happened, it was a good fight. If it weren't for those ridiculous suits, I would easily put Gavv above Gotchard in Reiwa era shows.
