Torchwood writer Jane Espenson has defended the last run of episodes.
The ten-part Miracle Day received a mixed reaction, with Espenson calling the show's fans "passionate".
"I've never dealt with a more passionate group of fans, so they weighed in very loudly about this last season," she told The Hollywood Reporter.
"[The last season] was the only season I was involved in. I was very proud of what we did."
Espenson argued that the final episodes had turned out "amazingly well", but suggested that Miracle Day had failed to match the quality of 2009 mini-series Children of Earth.
"I don't think you can ever beat Children of Earth.... which was an absolute masterwork," she said.
"But I thought we did very well. I thought we did things with that show that are not normally seen on American television."
Torchwood star John Barrowman (Jack Harkness) claimed last year that the show was "in limbo", though Starz CEO Chris Albrecht later indicated that a revival of the sci-fi drama is still possible.
