“Requiem For A Scream” (** out of four) was a half-hearted slasher thriller about a sadistic killer who preys on a group of friends (Cassandra Scerbo, Michael X. Sommers, and others) at a lake resort and intends on collecting all their screams and turning it into a murderous symphony. Cleverly titled thriller for those of us who remember “Requiem For A Dream” and features various homages to the “Friday The 13th” series. Not bad for its genre and professionally made but too routine overall to make much of an impression.
