Well first off you can't say anything about F4 because you haven't seen it yet. From the previews i've seen it looks like it's going to be a good movie.

As for her other movies. I've enjoyed them.

Never been kissed: Just a small part but it was a good movie. And she did an Excellent Job.

Idle Hand: Really liked this one. Very funny.

Paranoid: Her first Staring role. And IMO very Underrated. SHe did a really good job and the story was creepy and.. just weird...which was the point.

Sleeping Dictonary: Again she did a good job though her accent was a little rough. A period piece that dragged a little to long. But Had a very real feel to it. all in all a good movie.

Honey: Now this movie was way corny at times. But it really is a throw back type of movie. Very much like the dance movies from the 80's. Anybody that remembers those movies could appreciate Honey. Not Great but an Ok movie. And Jessica can dance her ass off.

Sin City:Haven't seen it yet so can't judge it. But from what others have told me it's a great movie.
