Same. Pretty much Nolan's worst decision as a director/writer was that character and both actresses he had to play her.
Rachel Dawes is very important in BB. Less so in TDK, but she still has a role to play in the film. Stating that the character is Nolan's "worst decision as a director/writer" is ludicrous.
Agree to disagree, but I stand by my reasoning. I for one feel this character with the way she was written and the way she was portrayed poorly--TWICE--was always the weakest link from any of Nolan's films. The first time she was portrayed by someone very attractive but too babyfaced and with zero convincing acting skill. The second time, by someone not attractive at all and who also sounded like she was reading from the page. Between two movies the character has failed to make me care at all for her.
Much as I enjoy Nolan's decisions with his movies, he's not flawless to me and the writing and acting of Rachel Dawes stands out to me and many others fans as example(s) of his poorer decisions.
