The Dark Tower series.
Harry Potter series.
The AOIAF series would have been great if R.R. Martin wasn't a fucking douchebag who doesn't know when to stop writing and adding more and more crap.
I've completely lost interest by book four. He's creating history at this point, not actually writing an engaging series of stories. The man lost sight of the fact that he's a WRITER, not a HISTORIAN.
But what can you do when the entire selling point of your book seems to be "Oh, I'm amazing because I kill off anyone whenever I want just for shock value instead of adding significance and driving characters forward in a straight-forward literary sense". The sad part being that he just descends into nonsensical writer crap whenever it's convenient for him, but doesn't seem to realize it.
