This Doctor Who story arc finds the time-traveler risking his life in order to save himself and his friend Peri when they become embroiled in a deadly war, and discover they've been infected with a disease that has no known cure.
In the "classic" Doctor Who series, this was the story for Peter Davison as the Doctor when the role would be inherited by 6th Doctor Colin Baker. It was hard not to like Peri as the new companion.
Christopher Nolan like he did with Batman made Superman darker and deeper. I thought it was silly to say the S did not mean Superman when it was true to original comic. Anyhow, I liked the movie and got the Blu-Ray.
