man i really do not know how i feel about Thorfinn as a character. i've never really liked or disliked him in any of the arcs, but i've found him to be a bit irritating and naive even though he has had so much experience and was surrounded by great people. he didn't grow at all from any of the events
i'm not sure if he's necessarily a "poorly" written character but i really think he's the least interesting out of all the major characters
i really hope i'm proved wrong in the future and that i grow to like him. i mean i'm rooting for him since he's the main character but that's about it
