It’s sort of the nature of the show. I might be wrong but I think honestly the only times we saw the new inquisitors was when they were facing off against our heroes. Hard to think much about them if we don’t get anything in the way of characterization for them.
I didn’t hate them but yeah fodder is the right word.
Also, I too liked the Jason Isaacs one which probably was at least 80% due to the Jason Isaacs voice.
