Decent coherent story without too much faff, proper nasty bastard Daleks again and Fantastic Voyage in a Dalek is a decent idea.
But everyone except Peter Capaldi is shit. He's very, very good as a distinctly nasty Dr [crikey finally they got that right]. So this ones a big improvement a strong B.
But jeezus no tension at all, when uncle threatened to kill them he might as well minced upto Dr and said, oooh I'll smack your legs cheeky.
And again action sequences are kinda weak and flimsy, stop doing shoot outs they look cack compared to the scenes in Easties when Phil gets his hands on a sawn off.
So it's good but no tension, no story. If it didn't have Capaldi this would be a C heading to a D.
