If anything, some of the music is in the same vein as pieces like East of Eden, Out of Africa, or even On Golden Pond (and I really liked her SP last year). The music is so beautiful that it's probably going to help people to like the program or pay attention more.
On paper, you're right. The pieces I've heard thus far definitely have Bill Conti's 70s/80s stamp all over it. It will have a familiar feel even though it's largely obscure outside of the usage in the 1980s/90s as mentioned above.
