The magazine was never regarded as one of the leading titles of the genre, but has received qualified praise from science fiction critics and historians. Science fiction historian Raymond Thompson describes it as "one of the most interesting magazines to appear during the 1940s", despite the variable quality of the stories. Critics Brian Stableford and Peter Nicholls comment that the magazine "had a greater importance to the history of sf than the quality of its stories would suggest; it was an important training ground".
