The anonymous reviewer in "Feature Reviews" in BoxOffice magazine's issue of 20 November 1961 had more to say, but nothing that was much better. He or she wrote that "little, if anything, is left to the individual viewer's imagination" in "Bloodlust!" and that star Graff "doesn't bring much conviction to the killer doctor part," while "the four young people ... emerge as one-dimensional actors." In summary, the reviewer said, "... this seems to let emotion-mad humans go on all out on a killing spree, and while the adventure-action audiences will find what's happening relatively engrossing, the discriminating won't be able to contain their bored feelings."
