8/10 show, 6/10 finale.
In my view it has the same strengths and weaknesses as OOO, but OOO executes it better overall. Very close in quality, especially with me thinking both endings were a bit rushed.
Gavv had better humor and action though I think at some points, but OOO was more consistent and even if the ending was rushed it was still better.
Gavv is the best Reiwa show so far for sure and despite it stumbling around the end a bit, I still enjoyed it.
