Re: Robin or no Robin?
I say Robin should be 15 if he's in this series. Just seems right.
I picture the reboot being Dick Grayson's story. Move to the sequel and Dick is 18 now, ready to move on. Introduce Tim Drake being a fan of Robin.
The third movie would adapt A Death In The Family and have Jason be killed. Jason would be 17.
The fourth would have Batman in a dark place until Tim convinces him he needs Robin. Tim would be 16.
