She is really gorgeous, and when she plays her characters, there is always something so genuine about it; that is what I like about her most.
When Stella from CSI: NY had those nasty "problems" with her "boyfriend" Frankie, Kanakaredes did an ingenious job on playing her desperation after shooting him.
Also, I really liked her in "Into the Fire", where she played that double-role as her twin and herself. For all those who only know her from her roles on TV: I strongly recommend that you watch her interview with Ellen deGeneres on YouTube, it is really funny. Melina tries to teach Ellen a traditional Greek dance.
