if you mean Gordon's son, no. Nolan has said these are the early years of Batman, 'Robin is out there in a crib somewhere'
Ledger was epic, stole the show, deserves Oscar nod. Movie overall was amazing and extremely badass, action scenes were great and brilliantly shot. A touch too long, and those sonar scenes were fucken disorienting. Vague ending will have to be explained in the third installment (which wont make it to theatres for a good number of years, most are saying). Some cool plot things that were unexpected. By far the best Batman film, and one of the best of the summer, but I don't think it takes my #1 slot for the year so far (right up there, though).
