Violence doesn’t end violence. It extends it.

크리스마스에 핫초코 마시며 재미있게 본 에피소드. "A Town Called Mercy"
아래 대사가 와 닫는다.
The Doctor: Don’t you see? Violence doesn’t end violence. It extends it. And I don’t think you want to do this. I don’t think you want to become that man.

"A Town Called Mercy" received generally positive to mixed reviews from critics. IGN's Matt Risely rated the episode 8.5 out of 10, calling it "a weighty, progressive, sumptuous and entertaining adventure". He praised Whithouse and Metzstein for setting the right mood and found the highlight to be the Doctor's moral uncertainty. Dan Martin of The Guardian described it as "a complex morality dilemma fizzing with sharp dialogue". He wrote that it was Gillan who "emerged as the real star of the episode", citing Amy's conversation with the Doctor about how travelling alone had affected him.

이것 때문에 우리나라 web 발전이 뒤쳐져도,
여기서 나오는 단물 먹는 회사들 때문에 아직도 쓰는 거겠지??

미국에서 있을때 인터넷 구리다고 생각했는데, 이런 걸 보면 미국의 인터넷 환경이 훨씬 낫다고 본다.

Gesture Recognizer

UIGestureRecognizer is the abstract base class for concrete gesture-recognizer subclasses (or, simply, gesture recognizers). The UIGestureRecognizer class defines a programmatic interface and implements the behavioral underpinnings for gesture recognition. The UIKit framework provides six gesture recognizers for the most common gestures. For other gestures, you can design and implement your own gesture recognizer (see “Creating Custom Gesture Recognizers” for details).
