This was an awesome movie. I went to see it with a date. Beware the movie is pretty long at 2 hours 40 minutes but I loved every minute of it. The level of detail in this movie, as the main characters try to solve the Zodiac murder cases, (and spend years doing it) is very cool. The performances by the actors were very captivating. I especially liked Mark Ruffalo as the soft-spoken, yet obsessive cop. Jake Gyllenhaal and Robert Downey Jr. are also superb. This is a great movie that will definitely make you think!
