Brisk/credible script, the small cast give good performances and the prosthetics and photography work well too. I picked this up for a £1, so expectations weren't exactly sky-high and the Full Moon logo can sometimes spell 'AVOID', - I was very pleasantly surprised. Earl Kenton did a great job with the script, and recognised the budget limitations his story would work within. He has created a small, dark and believable realm. All the actors, (particularly Jacob Witkin and Lorielle New) give very watchable interpretations and transcend the usual standard of performance you expect from this type of film. 'House of Pain' reminded me of two other great films - Stuart Gordon's classic 'Dagon', and the recent remake of 'She Creature'. Good stuff.
