What do you think of matt smith as the 11th doctor who?

personally, i think he's a good choice, apparently there have been some complaints that hes to young (26 years old) to be the doctor, but for gods sake hes supposed to regenerate and get YOUNGER! because we need someone with the younger/youthfull style like tennant was to play the role and not go back to the eccleston style (james nesbitt was considered i mean what the hell? no!) i'm sure they wont let the doctor get to the stage where he becomes a child (because i cant really see a 10 year old playing dr who) so they will just give him more regenerations like the master (plus i hope they bring him back for series 5 and jenny too that would be sweet) but anyway what do you think on the matter?
