Initial critical response to Fist of God was very average. At Metacritic, which assigns a normalized rating out of 100 to reviews from mainstream critics, the album has received an average score of 57, based on 18 reviews. Jesse F. Keeler told ClashMusic.com that he expected the mixed reception.
I expect a lot of people to not like the record, but I expect a lot more people to like the record now that we’ve reached a way bigger audience making it. It might sound like a calculated business move, but it was mainly a musical thing. We kinda knew what the reaction’d be, and we even told a lot of the kids on the message boards: ‘Well, a lot of you are gonna hate it’. It’s difficult, too, you know, because a lot of people have just discovered us, and they’re going to go on this record initially; but we didn’t want to make a record that was too ‘now’. We could have got a lot of the rappers - like The Cool Kids, Spank Rock and Kid Sister - but we tried to choose things and people that were more timeless. And, anyway, I love bad reviews, they’re my favourite things.
