She is an amazing actress. Her supporting acting in Pulp Fiction was hypnotising. She is beautiful, not conventionaly beautiful but still... just heartbreakingly gorgeous. Everybody says she is ugly, but i find her attractive. She is excellent in KILL BILL the emotion she portrays is excellent.
She further showed her talent and beauty in KILL BILL vol 2, this time she explored her "bride" character even more. Another great movie of hers is Gattaca, she was good in that too. In "My Super Ex Girlfriend" a crappy movie but still she was great in it. She is a great actress, one of my personal favorites.
