So bad they named it twice, it's a British movie set in New York that tries to out-Hollywood Hollywood with a grim plot that borrows heavily from the likes of Se7en and Saw.
W Delta Z is the inscription stabbed into the body of an electrocuted and tortured pregnant gang girl. Soon, her drug-dealing scumbag boyfriend is found murdered too. But who is evil -- or mad -- enough to take on the dodgiest characters in a bleak corner of the Big Apple?
On the trail of the serial killer (and boy, what a body count) are detectives Eddie Argo (Stellan Skarsgard) and rookie Helen Westcott (Melissa George). Eddie's got a dark secret, and he's as morally repugnant as many of the hoods he puts behind bars, or leaves on the street.
Soon the standard cat and mouse game develops, as the killer kidnaps one bad guy at a time and forces him or her to kill a loved one to be saved from torture.
It's not for the faint of heart, featuring the murder of a child by his druggie mother to save her own skin, and a particularly brutal home invasion and rape that sets the entire gory premise in motion.
It's a movie that asks how strong can your love be, even under the threat of torture. But, at its heart, it is dark, nihilistic and looks like it's trying to kill your faith in humanity.
A torture-porn movie that will leave a nasty taste in your mouth (unless you're psychotic yourself).
DVD extras: A gory effects featurette (hammering nails in fingers, etc), deleted scenes and optional commentary.
It's CSI on acid here as morgue pathologists go on a killing spree to impress their friends.
Milo Ventmiglia plays Dr Ted Grey, a brilliant graduate who lands a coveted post at a prestigous pathology programme in LA.
Brought out for an initiation night on the tiles by colleague Jake Gallo (Michael Weston), Dr Ted is shocked to find that a party-goer he met during the night turns up on a slab in the lab the following day.
Ted is soon inivited to join the gang as they kill someone by night, and try to solve how they were murdered back in work the next day.
It's really dumb, and even dumber is the fact that Ted's conscience doesn't last long and he soon joins the sick game.
Left on the shelf by the studio and sent straight to DVD, you'll soon see why.
DVD extras: Commentary track by the director; creating the perfect murder featurette; interview with a pathologist; and extended autopsy feature.
