I've been starting to have the same problem. I can still read and be somewhat entertained by books like Acacia, but they are losing their luster. The characters just have so much less depth and complexity to them when the author keeps the perspective so distant, and when there's so much time spent with secondary characters at their expense. I didn't need to see the events of Acacia through Leeka Alain's perspective, or that whiny little turd Rialus Neptos, or any of the others who weren't the four children and Hanish Mein. Focus, please. I don't need to be told anything and everything about the plot right when it happens.
What really bugged me about the book, though, was all the damn conveniences. The main characters get exactly what they need when they need it, and the author doesn't even try to hide his hand. *coughMenacough* Each of those instances (and they were many) came near to making me throw the book across the room and not pick it up again.
On the other hand, have you read Daniel Abraham's A Shadow in Summer? I read it just before Acacia, and it was everything Acacia was not. Meaning: damn good. I really need to get my hands on the sequel...
