Fom this trailer, at least, this one looks a lot more interesting. Bringing in Jude Law is a good idea. He's always legit. I didn't like Newt Scamander as a main character, he should just be a side character.
In fact, I thought all those grown-ups in Fantastic Beasts were dull. At the very least, Jude Law and Johnny Depp will chew the scenery.
Mostly, I think she should put some more kids in these. It doesn't feel right without kids.
