The Den of Geek, website had first dibs on the premiere episode called "Deep Breath" and it had nothing but praises for Peter Capaldi's debut performance.

The episode revolves around the Doctor trying to find his compass after the latest incarnation.

"Capaldi comes across as quietly broken, and really quite mysterious. He is also, and no bones about this, very Scottish. He's also every bit as good and as interesting as you'd hope," it said.

The London Telegraph's Ben Lawrence also lauded Peter Capaldi's debut performance as he noted the presence of nervous energy that the actor has been known to exhibit in some of his characters. "You always felt that his mood could turn at any moment, and sometimes he did, his unpredictability crackling off the screen," he wrote.

"This was a highly effective opener, showing that 'Doctor Who' is still the most intelligent, ambitious and eccentric show on British television. In his unsettling, cerebral performance, Capaldi fits right in," the Telegraph said.
