Excellent edge of your seat thriller....

Rating: 8/10 (4 March 2007)

Zodiac is one of those rare crime dramas that comes about and completely blows you away without any flashy action and gory-as-hell killings. It is simply about the investigation into the Zodiac murders and how the different parties involved communicated (or didn't communicate) to each other to help the case.
The acting is what really holds this movie together. Jake Gyllenhaal, Robert Downey Jr., and Mark Ruffalo definitely stand out the most and deliver superb performances.
Even the atmosphere of this movie is great. It really feels like the time period(s) that it takes place in as well. A great soundtrack (particularly at the beginning of the movie when the first murder is witnessed) really helps you step into the movie.
Overall, this movie is really great. The only bad side is the length. It is very long, but manages to hold your attention the whole time.
