I can honestly say without hyperbole that she does nothing
for me; her face looks like a Victoria-era doll, and her stock expression seems to be that of mildly annoyed boredom.
The fact that she refuses to be in any halfway-decent movie certainly doesn't help, either.
THIS, plus the chain-smoking hasn't helped her looks. In 10 years she'll look like Dr. Pulaski from TNG if she can't give up the smokes.
