“Alp” (*1/2 out of four) was a limp horror thriller about a young man (Yusef Abdur-Razzaaq) who suffers from sleep paralysis and comes home to confront his demons and is immediately besieged by frightening hallucinations that make him question his state of mind and his sanity. Intriguing look at a serious mental and psychological illness goes nowhere, and will only make viewers question why they wasted their time on this, rather than watch “The Nightmare” instead. Razzaaq is good but cannot overcome film’s exploitative and routine approach.
