I thought it was completely unwatchable. I couldn’t make it to the end. My kid likes it I guess.
I was intrigued by the setting but thought they skimped on the period details too much, so it felt weirdly bare and not lived in, compared to Hogwarts which always felt lived in and believable.
I’d have to double check his imdb page but I don’t think I’ve ever liked Redmayne in anything. There’s something off and unpleasant about him.
