A very interesting movie. I love Robert Downey Jr., probably always will. It was odd though to see him drinking and smoking, but at least he wasn't doing drugs in the movie (that I remember...).
I wasn't really aware of the Zodiac when the murders were happening or details were in the news so it was interesting to see everything involved. How awful to think you know who the murderer is and not be able to do anything about it. Or to lose your life in pursuit of it.
