I loved it. It was infinitely better in every way than watching Spock google Khan, or an equivalent to the "Space Seed" briefing scene.
Plus, it answered one of the big questions left over from the '09 movie - what becomes of Old Spock's future knowledge? We now know he's sworn to secrecy... well, unless something really
important comes up
(I just wish we'd gotten Greg's Old Spock-focused novel The Hazard of Concealing
in between movies!)
