Pretty epic. Love the episode's  snazzy Dalek redesign, the extra weaponry and just how cunning the recon scout Dalek is. Its new abilities are amazing too; I was genuinely horrified when it took over Lynn - much better than the Moffat era Dalek puppets.

And then when you thought the Dalek had been defeated with the microwave (what would typically be the RTD era Dalek solution) but the Kaled mutant had actually taken over Aaron Sinclair's body - possibly one of the best fake resolutions in any Doctor Who episode ever.
