For an exposé very little is actually revealed, but as a neon-lit trawl through '70s New York, it's worth a look.

Simply casting doubts isn't the same as making a compelling counterargument-or crafting a coherent film.
The Hollywood Reporter by Frank Scheck
Ultimately, there's not enough material to sustain a feature-length film, and the sloppy editing, cheesy re-enactments and cheap graphics don't exactly make for compelling viewing.

An unruly mash-up of terrific anecdotes and terrible teeth, grainy film and garish memories, Who Killed Nancy? cares less about investigating a death than about vindicating an accused killer.
New York Daily News by Joe Neumaier
The eyewitness testimony of dozens of punk-era survivors and hotel denizens has a disorienting effect, and everyone gets sidetracked, though the colorful anecdotes are priceless.

An unnecessary retelling of rock's dingiest "legend"--ever get the feeling you've been cheated?
Entertainment Weekly by Owen Gleiberman
The film offers evidence that Vicious spent the entire night out cold on barbiturates. It plants resonant doubts.
Despite the presence of Glen Matlock, Steve Dior and a handful of other punk rockers, plus a slew of oblique eyewitness who lurked around before and after the fact, the documentary soon bogs down in tiresome minutiae.
Fails as a detective story, but it does offer an entertaining look at the punk scene in the 1970s.
