Peace, at last...?

From the Radio Times:

On a flying visit to Cardiff, the Doctor is reintroduced to a familiar face. Shortly after, the Tardis spins out of control and its crew find themselves transported to the end of the universe. There they discover that the remnants of the human race are under threat from the savage Futurekind. Even the Doctor finds the situation rather disconcerting, but a committed science professor (Derek Jacobi) refuses to accept that his people are beyond help.

Derek Jacobi is as great as you'd expect, and there's engaging banter between Jack and the Doctor, but otherwise Utopia is a surprising clunker, seemingly created for its climax alone… thankfully, it's a beauty.

This episode (and the next two) have been hyped to promise great things and I think that what we'll see tonight will have The Professor regenerate at the end into Mr Saxon but we'll find out tonight if I'm right!
