Next to comedies, more than any other, the horror genre has been historically critically undervalued, perceived unfairly as comic and dispensable. In spite of the validity of its devoted following, harsher critics go so far as to nullify horror's purpose, snobbishly mocking it. What they've failed to recognise is, beyond the arbitrary artifice, these stories are exceptional vessels for wisdom of literary and social significance.
As a result of reviewers not always valuing the genre for what it is, many great horror movies have been misunderstood and underrepresented. With the exception of the 7th and 9th entries, which received negative reviews, the titles on this list hold divided percentages on Rotten Tomatoes.
