Ariana Grande's makeup styling looks really, *really* unnatural. Her look reminds me of the Wayan brothers' whiteface in the movie "White Chicks", or Ben Platt's "uncanny valley" face in "Dear Evan Hanson". What would be so "wrong", or unacceptable if Galinda were LatinX? I can't think of a single reason why they tried to make her look white. There's just no need for it.
For me, the song, "Popular" is much less believable coming from a character who's personal styling reflects her desire to be something she's not. Especially since she's singing it to another character who feels no need to hide, or cover up the fact that she's GREEN. Poor thing... Why'd Galinda feel a need to distort herself like that? Elphaba should sing the song to Galinda.
Not a fan of Erivo's gravelly vocal riff at the end of "Defying Gravity", either. I also agree with others about the excess of CGI.
So for me, what little was shown in the trailer sadly screams, "Nope". Not gettin' my money.
