I love Dune, but Herbert was all the way up his own ass by the time he got to God-Emperor. The books were still good, but his giant ego wasn’t helping. I mean, he, and a bunch of his fans, thought, or still think in the case of the fandom, that Star Wars ripped off Dune when they only have some surface similarities at best. It’s like claiming that Sonic the Hedgehog ripped off Mega Man on the basis that they’re both sidescrollers that feature a blue protagonist. But he was really fucking adamant about it, so people still keep repeating it.
