With clever, intelligent writing, a charismatic cast, and a compelling narrative, I wish I could watch this film for the first time once over again to relive the excitement of unraveling the mystery.

This fresh take on the franchise that finally leaves suburbia and takes on the urban setting of New York City more than makes up for the disappointing predecessor in Scream V.

In the mood for something dark and broody? Zodiac is a gripping thriller based on the true story of the notorious Zodiac Killer who terrorized the San Francisco Bay Area in the late 1960s and early 1970s. The film follows a cartoonist (Jake Gyllenhaal) and a journalist (Robert Downey Jr.) as they become obsessed with uncovering the identity of the elusive killer.
