I'm glad I'm not the only one who never found Julia Roberts attractive. Another one that does nothing for me is Gisele Bundchen, the so-called "Supermodel", who sissified...oops, I mean married, Tom Brady. Sorry, not so super.
Women who aren't great but somehow attract me include Gwyneth Paltrow (depending on what she wears), Jennifer Love-Hewitt (just a very pretty face), and, in her younger days on Friends, Jennifer Aniston - although I should add that the women on that show were average-looking at best so it wasn't hard to stand out.
