 Keith DeCandido , in a review of " Q @-@ Less " for Tor.com , praised the relationship between Vash and Quark and thought that it should have been explored further . Like Handlen , DeCandido also felt that Q did not quite fit in DS9 , but acknowledged that his performance in this episode was an improvement over his later appearances in Star Trek : Voyager . DeCandido described the boxing scene where Sisko punches Q as " wonderful " and " spectacular " . However , he thought that aspects of the plot had too much technobabble ; for example , the embryo plotline could have been resolved by a form of Customs procedure . " Ultimately " , DeCandido concludes , " none of this matters , because it comes down to one great moment of Sisko decking Q. Bliss . "
