As someone who loves true crime and reads all kind of stories about serial killers it's a shame that i never got to see this movie until now.
It follows the invastigation about the Zodiac killings that happend back in the 60's and 70's in San Francisco.
The movie is rather long but it needs the time to get you engaged in the riddle and all the shit that happend back then. One of my favourite scenes was the basement scene. If you've seen the movie, you'll know what i'm talking about.
However don't expect the movie to have a satisfying ending because the Zodiac Killer never got caught in real life so this movie lets you guess as well.
Loved the acting in this and it's unbelievable how good Jake Gyllenhaal is in this.
