Blobfest kicks off July 14 at the Colonial Theatre in Phoenixville. It's a multi-day celebration of B-movies and so, in its honor we've compiled a list of the 25 best B-movie horror films of the 20th century.

To make our list, we pulled the 75 most popular horror films from the 20th century with the b-movie tag from IMDB. Then, we cross referenced that with Rotten Tomatoes scores, where the higher the percentage the better the film. The highest-scoring films appearing higher in the ranks, obviously.

Here is a countdown of the films that made our top 25.
