Best Rachel Dawes HANDS DOWN!
Gyllenhaal was to hollow there was no emotion in her performance in TDK while Holmes was excellent as Rachel she played the character with full of life. You cared for her while with Gyllenhaal was really hollow so it was impossible to be sad when Rachel died when Gyllenhaal was her.
If Holmes had been Rachel in TDK you would actually feel sad like Bruce did when she died
CW network sucks ass!
