I listened to a few, and I definitely agree about Dark World. It's normally not a track I notice, but the new flute sample really makes it. Others create more problems than they solve -- Locke's theme sounds terrible, for instance. I think it's poor mastering overall -- when the default Garritan mastering works, the track works. When it doesn't, it doesn't work.
He said upfront that it was essentially midi rips with Garritan sounds subbing in -- what did you expect?
