Moria gives it 4 out of 5 stars and says, "This was the film that showed that Roger Corman was a serious filmmaker and had his work re-evaluated by critics in the 1960s". 1000 Misspent Hours says,
the film was a big success for the studio, and it is hardly a shock to see that AIP continued producing Poe movies long after Corman got sick of directing them.Classic-Horror.com says, "Although Corman's skills as a director had not yet completely matured, the adaptation was solid, both in concept and execution" and agrees with other reviewers that this one is the best of the Poe series.
