A few thoughts: Larry Blamire is the kind of director that you either love or just don't understand. While not on the same level as The Lost Skeleton Of Cadavra (one of the greatest parodies ever made), this old dark house send-up is filled with hilarious characters, one-liners, and the perfect balance of absurdity and spot-on imitation of the subject matter. This is the third parody by Blamire and his crew of regulars, and you can definitely tell how familiar they are with each other, as their chemistry and comedic banter is top notch. This familiarity is infectious, and by the end of the movie you'll be so wrapped up in the fun they're clearly having, there's no way you can't picture behind the scenes moments of them all bursting out laughing in between takes. If you aren't familiar with old dark house movies, you probably won't get all of the jokes, but the humor is so rapid fire and off-the-wall, odds are you'll still find plenty to laugh at. It's an affectionate parody of a subgenre that's faded into obscurity, and the production is detailed and clearly produced with great admiration.
Who would I recommend it to? Anyone who enjoys throwback genre parodies, particularly those who like or are familiar with filmmakers like Larry Blamire or Christopher R. Mihm.
