Review title: Not a bad time travel story even if it is a bit "played out"
Product review: Different versions of the "evil scientist" antagonist are traveling through time doing both evil and good, trying to both harm and to protect. It is up to Kirk & Co. (mostly Spock) to set things right. Although there are some problems with the story - most notably a bad characterization of Mr. Scott (I doubt he would be so quick to take sides against Kirk & Co.) - it does have its moments. In particular, the interplay between Spock and McCoy, the subplot involving Mr. Sulu, the characterizations of the security personnel and the Captain Hunter character.
