I've been keeping an eye on some of the bigger WoT websites and youtube streamers, and overall, it seems the majority of the fans are fairly happy with what's been adapted. Of course, most of those people have been engaging through the streamers with Rafe (the showrunner) and most of the cast and screenwriters. Who have been slowly filtering out potential changes and how and why things are being adapted in specific ways. A great way of managing expectations.
It's interesting, they flew a bunch of them out to London for the premiere event, and some of the actors were engaging with the streamers in that whole "I've been doing interviews and q&a with you for the past 2 years, great to finally meet you, how are the kids? did you enjoy the flight? hows the hotel?"
