While I think she is talented and very beautifull I still feel that she is over rated in both camps a little.
She was sensational in Leon. I doubt she will reach those levels again. She was very good in V. Apart from that I haven't seen anything mind blowing from her in terms of acting. I'm not saying she's not good either. She gave a decent performance in Closer but that was over rated because of what she had to do in some of her scenes. But I still feel on times people are just a little to quick with the praise.
Good actress? Definitley.
Brilliant? Not for me.
