No group is a monolith, of course there isn't a Sami hivemind agreement about the movie all in perfect harmony with each other. But what no one needs is Americans who never heard of the Sami until this movie talking over them.

And a movie of a Scandinavian story set in Scandinavia with characters from a Scandinavian minority is just about the stupidest place ever to complain about not featuring US "children of color". Although you seem to be super into counting up people/tokens and subsuming their whole character under a single fetishised aspect of their identity so..(I have to say I don't have much hope for Moana based on what's come out so far though, unfortunately.)
