I love William Castle films because they are well-made cheesy fun. Films such as STRAIGHT-JACKET and THE TINGLER are classics of the 50s and 60s shock horror and they are definitely an acquired taste. Some probably see them as pretty tacky but lovers of the genre love this tackiness--this makes the films so wonderful fun. This spirit of silly good old fashioned fun is what makes this short documentary a must-see. Instead of taking a super-serious and dull look at William Castle's films (something Castle himself NEVER would have done), the film is very much tongue-in-cheek and laughs at the films while lovingly applauding them. I especially liked the great interviews with Darryl Hickman--he laughed and laughed and seemed to genuinely love the films while acknowledging their cheesiness!! All the great background behind the film and interviews did a lot to help infect the viewer with a sense of fun! Were Castle's films great art? Of course not--but were very entertaining. In fact, as I watched the documentary, I found myself laughing repeatedly about all the funny anecdotes and background information.
