Can Rpbert Downey Jr. Act? YES.
Can he pull off the roll? YES
does he physically represent Tony Stark? the answer is NO.
Neither did Micheal Keaton, when he was cast as Wayne and look how that turned out. Infact Wayne has always been portrayed as a 6'2" 220lbs of muscle, Keaton was 5'8" around 160 lbs, coming off Mr. Mom movie, but he pulled out a fantastic performance.
I think RDJ will do fine, besides its way too early to start saying this is a bad decision.
