Honestly, I have no idea. Based on every objective metric this should rank way above the first season. The overall plot is better structured and executed. This in turn allows for the subplots to come into their own as well. The actors really have anchored themselves in their roles. I know I didn't have anything good to say about Triss' actress, for example, but she's really done a 180 for me. The scripts are way better then in season one as well, tighter, more focussed. The CGI is leaps and bounds above season one, which helps tons, combined with massively improved costumes, to sell the world. The sets? My god, they finally made use of and constructed some really appropriate and good-looking sets and combined them with real places, where possible.
Is there still tokenism? Yes, though it's less egregious now that the rest of the show has improved so much, so at least for me it doesn't break immersion that much anymore. Are the costumes and the CGI perfect. No, there's of course always room for improvement. The Nilfgaardian armor scheme is now bronze on black rather than having black as the primary color, which is weird, but overall their armor is ten leagues better than what we had in season 1. The Wild Hunt's armor would be better if it was simply copied from the games. Some of the compound CGI shots where they used real places as the base look a bit weird. But given how substantially they have improved upon all of that compared to season one it's almost nitpicky to dwell on it too long. Because now they've actually managed to make it look like a lived-in world.
I for one can't see why this would rate lower than season one. And you know how much I shat over that one...
