She's usually got at least one boob out, which I'd say is a pretty attractive character trait in a woman, and she's sporting a remarkable pair of assets. Mostly though, I just think her face is gorgeous and I like her voice (when she's not being whiny). Seems like a lot of Russian women have deeper voices. Guys too, actually. Maybe it's just the way the language is constructed. Come to think of it, Leora has a rather pleasant voice too, I'd say.
It's all a matter of taste anyway. I can certainly see why Jessica and Nicole appeal to so many guys in this forum. Nora, not so much - she's really not my type at all. That said, a lot of guys seem to find her very appealing, and that says something good about living in a world full of diversity, so I'm glad about that.
Also, this movie is actually even worse than I remember.
