Cannot believe this was rated 7.9/10 when I went to see it

Rating: 4/10 (19 March 2007)

If you are interested in paying 10 bucks for a 3 hour documentary history lesson on a 1960 serial killer case which has no convicted suspect till the very end of the movie, go see this movie.
But I have to say, between the Zodiac movie and calculus class, I'd rather choose Calculus. They're both equally boring, but at least I'm learning something in Calculus.
My friends and I were ready to hang ourselves and make someone send our bodies to the director with a posted note stating: you bored us to death.
4/10 is generous
