Query: A horror, but not a thriller

This is another Universal horror film from the 1940's, when both budgets and quality levels shrank dramatically. "House of Horrors" is one of the worst of the genre, with an inept cast and an idiotic plot. The only cast member capable of generating either interest or sympathy is Rondo Hatton; the others are forgettable. Interesting only as a curiosity. The real horror here is the astonishing level of ineptitude it took to make a movie this bad.
