His take is a bit much...
I love Dune 1 and 2, and anyone who is paying attention knows that it rightfully shows the dangers of a rising Messianic figure, just as the author intended. Frank Herbert through fiction showed an interesting take on how religion, strongman and wars are interconnected and cyclical. But to say that he didn't have some problematic views (and creative decisions... Duncan...) would be an understatement.
