Really appreciated Villeneuve adding small scenes to the movie like the gardener watering the date palms and the ecology outpost. It rewards people who read the book and also helps people who are just watching the movie with understanding the world.
Curious to see what other tid-bits from the book they will keep in part 2. Hopefully we can see some Fremen Sietches.
On another note, I've always wanted to write a load tester library, I would call it Gom Jabbar. If the service falls over it fails the test.
