I actually liked Vulpes Inculta's voice acting. Androgynous and ominous without sounding overdone. Raul was a bit meh, mostly because, for some reason, Danny Trejo limited his range a lot. It works though, and it's actually more convincing as a ghoul's voice than the default ones.
Matthew Perry was a mixed bag, he nailed the intro, ****ed up completely the lines he speaks when he meets the Courier again but also pulls off some of Benny's dialogue with him with surprising subtlety. Overall he wasn't completely awful but I honestly excepted more out of him. I've got no problems with Veronica and Caesar (it was a weird choice but a good one imho, gave him a lot of character without making him sound clich
