Yep. Too much action for my taste. Dune 1 was better and much closer to the book.
I tend to agree and prefer Part 1 as well.
There are significant differences from the book but they are surprising not damaging to the underlying themes of the novel. Strong references in Part 2 to the "religion" of the Fremen and Paul's messiahship are probably a setup for the third movie, presumably based on Herbert's sequel, Dune Messiah.
