Yep fair enough! I see the "machines take over" bit as a B-story, and not very fun (probably the same instinct you have about it).

It's a great movie, but I'm with you on the general trope. Battlestar Galactica reboot I liked (for the soundtrack). Terminator I liked (for the time travel). Matrix I liked (for the philosophy). Other than those, machine dystopia stories seem tired & one-dimensional.
