In anticipation of TP2017 I've been in the process of rewatching all of Lynch's stuff (except for the original Twin Peaks cus I'd already re-watched that plenty of times). So his films are all pretty fresh in my mind.
I doubt that music is very representative, it is just teaser music after all. I hope there's lots of good new Badalamenti pieces in the show. I love the old soundtrack music and I'm sure versions of those songs will appear somewhere in the new series, but I hope they don't lean too hard on it.
I thought the BR2049 trailer looked pretty nice too. If nothing else it'll be worth seeing just for the cinematography alone. I don't know why people b###h about Ryan Gosling, he's a good actor and usually chooses good films to star in. He's not that expressive or anything but he usually gets cast in roles that fit that style, if he's playing a robot or replicant or whatever in BR2049 then he'll be well cast. I've been meaning to watch Enemy, sounds like it would be up my alley.
