I actually think the Darktrooper theme is great. I never listen to dubstep, but I’m glad Ludwig Goransson is drawing on so many different styles and making his soundtrack experimental.
Just listening to the opening seconds of “The Mudhorn” in season 1 showed me I could expect anything from the score, and I mean that in a very good way.
Even when he used familiar themes such as the march of the Resistance he re-did them in an unique style.
I really thought the effects on Luke were great, and for a long time I couldn’t figure out if it was Sebastian Stan or a stand-in with Mark’s face. Of course the CGI becomes more noticeable when one is looking for it, but it felt much more natural than, lets say, Leia at the end of Rogue One.
