Yeah wow! i liked how they referred back to the original idea of the master saving the doctors life in what would have been Roger Delgado's final appearance of the master with the 3rd doctor had he himself not sadly passed away. What happened to the master, did he go back with the time lords? My only complaint is i think they dragged the ending on abit to much. David tennant, John sim and Bernard Cribbins where pure awesome and Bernard's acting, nearly had me in tears! Just a shame we couldn't get a wee preview of the next series.
PS I think Matt Smith is going to be a brillant at the role, don't care what anyone else says.
