So you mean my preferred method of reading it while watching tv and also surfing the net is not a good idea?
I read about forty pages of 'God Emperor' last night and really found it to be off to an enjoyable start.
If that's what works for you, great.
I don't find God Emperior's story to be that difficult, and thats the most important part. I tend to just glance over the boring philosophy stuff and everything involving visions/the golden path in the books after Messiah, and I definately remember the books after GE not being so full of that stuff, so I'm fairly sure my opinion of GE won't change. It has a decent story thats not as good as the first three books, combined with probably the stupidest looking tyrant/villain I've read in a sci fi book (Leto shpuld have just stayed as a human in a living suit, whenever I imagine him as a giant worm with tiny arms and a human face I just find it funny, and not very threatening). I call him the villain because he's the biggest evil in the series up to that point (although you could arguably call Paul Atredies the most evil character, but I'm sure Leto beat Paul's kill count early in his reign). The villains of Heretics of Dune and the other later books were worse, but Leto is the probably the worst villain in the history of Dune's universe up to that point outside of the Thinking machines.
By ignoring the "philosophy stuff", you're missing out on a huge part of the story. Leto II as the Tyrant is a repository for millions of humans' memories, from uneducated ditch-diggers to scholars, rulers, and all kinds of others. It gives him a philosophical perspective that no other person in the history of the human race has ever experienced.
I won't disagree about his being a villain, though. I found Leto II thoroughly unlikeable even in his baby character at the end of Dune Messiah, and he only gets worse.
