I don't plan to see Hide and Seek but...
I hear
Dakota Fanning is excellent.
One of the best CSI episodes (in my opinion) is from the first season, with little Dakota Fanning (age 6) playing "Brenda Collins" in the episode "Blood Drops". That's the one with the father, mother and brothers getting slashed up and the older "sister" turning out not only to be the one who did it, but also was the victim of years of rape by her father, which produced the little girl Brenda, who was also then molested by her father-grandfather. Oy, I know. Jorja Fox's character takes care of the little not-talking girl throughout the episode, and it's all very touching and I cry a lot every time I see it...but the point is that Dakota Fanning did a great job then, and I hear she does a great job now. I also hear she was pretty darn good in
I Am Sam, which I also didn't see. One can only hope that some terrible child-star fate does not befall the kid.
