From the BBC;

Richard Beech, in the Mirror, agreed Capaldi had "all the hallmarks of a great Doctor".He called the 80-minute opening episode, entitled Deep Breath, "an impeccable debut"."If you watched Deep Breath and you don't want to watch the rest of series 8, then there truly is something wrong with you," he wrote.

I enjoyed it. Not the best episode ever, but I’m certainly interested to see where it goes.
