My reaction
Concept: It answers that burning question, "If they've discovered half a dozen means of time travel throughout the original series, why aren't they time traveling more often?" The answer: "What? They time travel all the time. It ain't no thing."
Story: So timey-wimey.

Subjective Rating: 7/10 (Good, ). Baby Spock is annoying, but if you can get past the ridiculousness of the setup, it's a novel story.
