The good:
Ridley Scott is not directing
Dennis Villneuve (Of Arrival, Enemy and Sicario) is.
Ryan Gosling is probably the best casting choice
Original music from the first movie (at least in the trailer)
The bad:
Blade Runner global drying: deserts, sandstorms and no rain? How on earth can we have Blade Runner without rain?
Rutger Hauer is not back
The meh:
Han Solo-Deckard is back. I guess the money was good enough to lend his face to the sequel of his "...not favourite movie"
The factoid:
movies set in the 2040's are crap. Also Wiki's list does not contain 2046, which is the only good one ...
