Personally, I find that a lot of LISP hackers put way too much logic into a single form or method rather than breaking it into smaller components that can be composed together. And I think that's often why we see frustration with LISP is that you'll have something that is indented really deep when it could be a much smaller function that's leveraging other functions. It's even worse in certain lisps like Clojure, where you'll see a lot of shorthand symbolic stuff, like for anonymous functions, or when you're using core.async, where you look at it and you think, is this brainfuck?
