 Christopher Bahn of the A.V. Club was less positive about the episode , grading it as a B- . He praised the early scene where Amy was abandoned for the " zingy dialogue " but found himself " enjoying the cleverness of the explanation without really buying into it " . He expressed confusion at how the time @-@ shift worked and thought the problem was too thin to carry out the whole episode , and that Amy 's abandonment and love for Rory which was left " [ didn 't ] pull it off " . He thought that the two Amys seen in the mini episodes " Space " and " Time " were more fun to watch and the episode did not reveal anything new about Amy and Rory . However , he praised how the decision the Doctor had to make was portrayed .
