Maybe I’ve just watched too many cartoons, but I find it a little hard to maintain my immersion (?) while watching the show when new characters are introduced and they’re very clearly voiced by Azula, The Green Lantern, Lex Luthor, and Optimus Prime.
I’m only a couple of episodes in and the only voice that really came from left field after checking the credits was Walton Goggins - he uses a strong southern accent in nearly everything I’ve seen him in recently so it’s interesting to hear him speaking “normally”.
