Expertitis is not a thing and your criticism is based merely on public perception of the book and not the book itself. In case it wasn’t clear, I disagree completely: Ulysses is very worthy of the honor. It is as approachable as it is lofty.
It’s not, really. If you try to read it you will fail miserably with a completely unenjoyable experience. It’s kind of like The Bible or The Odyssey, anyone who recommends it is out of touch.
