What's the scariest scene? (other then the basement)
I know most say the basement scene is the scariest but for me I already know the real Graysmith is alive and well (a liar and an idiot, yes but still alive). For me it was funny seeing Bob Vaughan messing with Graysmith, especially when he was smirking when he said goodbye to him.
For me though, I think the Riverside scene was chilling. Showing photos of the Cherri Jo Bates crime scenes, the letters and the desk top poem can be a little chilling. The fact that they're suspecting that maybe this was Zodiacs earlier work, or maybe Zodiac copying someone else.
At the same time I felt like it gave a little tribute to a young girl who probably had her whole life ahead of her but never got any justice but will at least be remembered as films last forever.
