It’s brave making a movie about an unsolved series of killings; after all, you’re proclaiming from the start that there will be no neat ending, right?

Instead, this film follows a group of characters involved with and affected by the Zodiac murders. The police on the case, the journalists reporting it. Mainly, it tells of the cartoonist who became so obsessed with the case that he quite possibly solved it – but at what cost?

I did enjoy this movie, but it’s quite unlike anything. There’s no real suspense, because you know there’s no answer coming. The various stories of lives entangled in the case are interesting, but this is ‘real life’, not fiction, and as such most of the threads just peter out.

I suppose ultimately the strength and weakness both of this movie is that it’s entirely about the surrounding ‘cast’ rather than the actual serial killer. Kudos for managing to sustain interest in the story even when the killings stop. Marks off for ultimately not being quite as interesting as I just thought the whole thing could have been.
