The pin sharp dialogue and perfectly paced story is accompanied by a first rate cast – most notably Robert Downey Jnr’s hack Paul Avery and Mark Ruffalo’s dogged homicide detective David Toschi. The story veers away swiftly from standard serial killer fare to intense procedural, focussing on the obsession of the men trying to stop Zodiac. And the real accomplishment here is that audiences will feel their regret, because to this day, the killer has never been caught. Despite this and the intimidating running time, those with the patience will be rewarded with one of the best crime thrillers in years. -–Luke Mawson
