Password rotation for your "emergency" system account (the one that shouldn't be root) still needs to be rotated every time someone with access leaves or changes job roles.
I mostly liked it, but it did one thing I dislike in prequel movies: attempt to explain everything. It isn't quite as bad as the train chase from Indiana Jones and the last crusade which tries to explain all of Indy's quirks and wardrobe choices in a 10 minute scene... But that felt like the gist of the movie to me.
"Contact" for a similar reason. It's a mix of all motivations, along with people's general mistrust of each other.
