normal Star Trek commander type. Carson was also pleased to work with Crosby and Goldberg. The main cast enjoyed the opportunity to play their characters differently. The unusual degree of friction between characters provoked some concern with the producers. Berman, for example, was afraid that the episode was pushing the alternate timeline too far. Ganino and Stillwell visited the set frequently during filming.

In contrast, Tor Books' Keith DeCandido wrote that while the guest stars were excellent, Tasha Yar's return for a "TV death" is the episode's major flaw: "It is, in short, a scripted death, and you can see the marionette strings", he wrote. Film critic Jordan Hoffman wrote that the episode is "heavy, Philip K. Dick-ian stuff that actually takes some thought to
