So from the start, this show takes great advantage of 4k / Doby Vision. Inky blacks and great, bright lights. The cinematography is also (mostly) fantastic.
Sam Waterson (of Law and Order fame) is in this which I love. Music is also solid.
My biggest gripe after episode 1 is the dialogue is severely lacking. I'm not sure if thats b/c dialogue in the 1880s was fairly basic or what, but its lacking and not very engaging. B/c of that, the acting itself kind of falls flat.
BUT, its the first episode and they are often not the best at showing what the show has to offer.
Definitely sticking with it.
ALSO, it has an enjoyably title sequence...and when a show has that, I'm usually sucked in.
