I agree it can be hard to read at first, but after learning the syntax, it's not hard to read. It's also about what the language allows you to do (or prevents you from doing) that determines, to me anyway, the utility. I love Objective-C but it allows you to do a lot of things that can lead to bad code (mostly related to state and hidden side-effects). FP overall is a paradigm that helps prevent you from doing that and helps you rethink and describe problems declaratively.
