I'd say Gavv ranges from a high B to a low A as a whole.
Finale's fine, I like the overall closure it's given the cast while being somewhat open-ended on things like Masaru being open with telling Shouma he knows or the remaining Granutes in the world. Does well to show that it's not the end of their lives, even if it's the end of the story.
I'm a sucker for finales where they cycle backwards through the forms to end on base form, so despite people complaining about the action I can't see the reason, unless they're just being autistic about power levels.
