Death on Demand (2008)

A rich college student decides to launch a business venture in reality TV with a pay per view web cast.  He offers three couples $5000 to spend the night in the supposedly haunted house of a mountain climber who killed his entire family.  The house is filled with web cams and the couples need to survive the night and find the exit by following clues that he's left for them.

The webcast starts with a seance in which they call the spirit of the mountain climber who arrives from the beyond complete with climbing gear and an ice axe.  The house isn't that big and with all the web cams, the host should have noticed him before he'd killed some of the contestants.  See that house on the cover?  Yeah, that's not the one in the film.  It's probably 1/3 the size.

The characters are obnoxious and you don't care whether they live or die. Actually, you prefer that they die.  The worst are the annoying shrieking girl and the girl with the weird voice.
