As far as minimalist covers go that one's not to bad. Generally speaking, I'm not a fan of them though, I much prefer a good graphic, colourful cover like my original paperback - I had to get a 2nd one because of the condition of my 1st, I like it too much to have it fall apart.
I had the red hardback with the clown face in the warped house for a bit but gave it away when I found the paperback - the hardback was just to big and awkward for a reading copy.
This is the current UK cover
I still prefer my original paperback cover.
