I think maybe you have to be in a certain frame of mind to enjoy Murakami. I recently read The Wind-Up Bird Chronicle and loved it, despite giving up on it years ago. I also read Kafka On The Shore several years ago, but felt a bit 'meh' about it, but I think it just wasn't the right time for me. Because his books are so surreal and strange I think you have to be thinking in that sort of open-mindedness way at the time you read them.
1Q84 is on my wishlist, but because it's such a big book I'm going to wait till I really want to read it before I start it. I don't recall hearing that many 'meh' reviews about it though. Most people are positive about it.
