you guys do realize that their is more than one way to do robin right? Personally I thing Shai would be too old as if they are going with dick grayson it would have to be when he was still fairly young, and the same pretty much goes for the other robin's. Their are two ways I could see it working out effectively:
1)You go with Dick Grayson and the whole his parents were murdered during a circus routine thing, and have Bruce maybe already having tracked the mob to the circus or something, and out of sympathy for when his parents were killed he adopts dick and tries to keep his secret identity a secret from him. It would be great because you would get to see christian bail act really awkward around a kid and Alfred looking at him scornfully/pathetically. And eventually, against Alfred's wishes he starts training the kid because he realizes that, the same way he did, that he would want to get revenge anyway and it would be better if he had discipline and skills if he was going to do it, and in the end the new robin helps him (although the robin suit would need a big redesign to fit into that universe). Over all crib more from batman the animated series and less from the two batman movies with robin in them.
or
2) Go with the, scruffy street kid thing and but sort of like the fake batmen from the second movie. After batman goes into hiding at the end of the second movie the crime rate rises, especially in the poorer areas of the city. Some young kind, who had a patent killed by street crime perhaps, decides that if batman isn't going to protect them anymore he might as well. Granted he isn't very good and as batman comes out of hiding more he finds that the kid is way over his head, tries to discourage him, but finally realizes that the kid has the same type of fire that he had and (again like the 1st one) if he doesn't train this kid he will go out anyway and get himself killed.
Both of those could work well in the universe of the new batman movies, and could result in a good movie. Also, nether of the parts would really fit shai Lebuff, which is a good thing.
P.S. Oh and about girl with a dragon tattoo, very good, but not for the faint of hart. Their is some really graphic stuff in there. I work in a movie theater that has it and I have seen people walk out of the movie and sit in the lobby because they found the movie too traumatizing, and this isn't a case of saw style murder porn, just of a director depicting things with more realism than most movies give them.
