Eva is definitely one of the sexiest women on tv TODAY, but not of all time by any means. Just like the brits or the french to come up with Eva as #1, Jennifer A as #2, Kim C as #3, etc. of "all time" with no mention to the truly sexy women of two or three decades ago who were able to exude sensuality without acting like sluts. To the brits and frogs, slutty is sexy. They have no clue about the how subtle and alluring is so much more sensual than the slutty and easy bimbos of today.
I'd go along with that. The top 5 today (IMHO only) would be Eva, Rose McGowan, Evangeline Lilly, Kristin Kreuk, and Mischa Barton.
