You get over it really quickly once you start actually using it. I find it basically impossible to read Clojure outside the editor in any meaningful sense.
Lisp is tricky. Pretty much every programmer for whom it's not their very first PL hates it initially, but then there's a time, a threshold after which no other language feels more readable than Lisp.
Using structural editing idioms and the REPL, usually makes the process less vexing.
I think for some people it's an aesthetic knee-jerk reaction and the fact that it's "unusual" for a programming language. It's not like their brains "can't grok" -- it's just syntax after all. People don't tend to have that reaction to xml for some reason. It's data, so it gets a pass. But then this is code-as-data and they have to break that barrier conceptually and then get past the aesthetic knee-jerk reaction.
I went through a similar phase decades ago with Common Lisp. It takes a week or two. Now, it’s quite a natural syntax and I see the parens as a huge benefit. I like Clojure syntax even more than CL and Scheme because of the map and vector literals.
