Hopefully, he will have scaled back a bit from the grand overarching craziness that was Pandora’s Star and Judas Unchained. They were both wayyyyy too long and complex. I believe that people who complain about world building have Peter Hamilton in mind.
Don’t get me wrong, I like his writing. It is original and interesting, but sometimes you just have to cut to the chase. Tad Williams has the same problem. And don’t get me started about Terry Goodkind and his inability to finish a story.
If you want to read some good stuff by Hamilton, stick with the Night’s Dawn Triology, and the first two Greg Mandel books.
