Having just binged the three seasons, I'm happy enough to come here and give it a positive review.
First and foremost I think the effects were really something. Everything felt quite immersive, there were rarely times that something felt too fake. Some of the imagery was exactly how I imagined from the books, for example the abyss and the mulefa world.
Some of the performances were amazing and award-worthy. My favourites were Ruth Wilson as Mrs Coulter, Will Keen as Father MacPhail. Simone Kirby as Mary and. Ruta Gedmintas as Serafina. They each really brought their characters to life, from the tensions of Coulter and MacPhail to the serenity of Serafina and the more ordinary yet inquisitive Mary.
Some other portrayals I was less keen on, including the two main characters, though I think they improved towards the end and delivered an impactful finale. I also wasn't completely sold on Asriel, perhaps just a bit too different from my personal image of him. My other gripe is that I felt there wasn't enough time for some characters to be properly fleshed out and felt for, which led to some scenes being less emotional than they could have been.
Regardless, this series overall did the books justice and I would definitely recommend it.
