Pulse (2006)
"Pulse" is the reimagining of a Japanese horror film about a dangerous wireless signal with the ability to take over the world. The original was hailed for its unique atmosphere and creep-factor, but the remake was just bland.
The Roommate (2011)
Minka Kelly and Leighton Meester play the leads in this "Single White Female"-inspired horror flick. Meester plays an obsessive roommate who wants to take over Kelly's life, but the events are just too dramatic and evil to ever be believable.
