She's too skinny.

Just look at Maggie Q, the star of The CW's "Nikita" (9 tonight). And in that scene she's supposed to be so hot, a man surrounded by bathing-suited beauties sends them away to get close to her alone.

I dunno, is seeing a ribcage sexy?

For me, that was the flaw in this latest turn on the Luc Besson film "La Femme Nikita," about a revenge-seeking heroine who is a sexy, smart butt kicker. Fully clothed, Q is more convincing as someone who could snap a big man's neck. And overall, she's very good in this role; I'd go as far to say that it's equivalent to Jennifer Garner's star-making turn on "Alias."
