Moana looks super cute and Disney has been dominating this year in terms of both success and quality.
Fantastic Beasts... meh. I know it's connected to Harry Potter and I've never been a fan of ha so I'll pass. Even as a stand-alone film I'm not interested.
I saw both already (on the same day lol) and I was very pleasantly surprised by Fantastic Beasts and disappointed by Moana... however, Moana definitely stuck with me more in the weeks since and I find it more rewatchable.
