I finished my reread of God Emperor. It was better than I remembered. Its philosophy, while still not something I particularly liked, was atleast more interesting to read than in Children of Dune (it flowed better because it was mostly done in conversations than in pages of description). It still had some weird parts. Siona did a really weird turn at the end after Leto's death. Why the hell does she want to mate with Duncan now? She didn't want to, then immediately after Leto dies she thinks about how she'll have to seduce Duncan. That just came out of left field. If the story had written them becoming closer or something (like Leto planned) it would have made sense, but she just randomly decides she's going to seduce him. Also, Duncan was an idiot. Where did he think Hwi would be when they killed Leto? Of course she'd be right next to him, and would fall off the bridge when they destroyed it.
Another thing I noticed is that Frank Herbert got really creepy a few times. I could have done with out the sex references (why is Duncan climbing a wall need to be described as..."exciting" Nayla?). Also, the philosophy about the Fish Speakers was not just boring, it was kind of creepy. I also didn't need to learn that Duncan really doesn't like gay people, that seems like the kind of fact that just makes Duncan seem like an unlikeable a-hole. Its not even like it was a throwaway comment, its a full conversation that just made me wonder what the point is. I guess it was more of FH's philosophy, but I just don't see the point. If it was philosophy, I'm not sure what side FH was trying to support, either.
So, overall, this is a good book, and even though it has a good amount of philosophy I don't care about, it gets derailed by it less than Children of Dune did. Next up will be Heretics of Dune.
