A classic horror from 1973, presented as a double feature with Last House on the Left, Don't Look in the Basement (or it's alternate title, The Forgotten) is a low budget horror (blog post) movie set in an Asylum. The premise is interesting, but the twists more than obvious. However, does (blog post) the acting and presentation make (blog post) up for that?
