A witty, exhilarating and mind-expanding exploration of the word of our times - data - with mathematician Dr Hannah Fry. Following in the footsteps of BBC Four's previous gleefully nerdy, award-winning maths films The Joy of Stats, Tails you Win - The Science of Chance and The Joy of Logic, this new high-tech romp reveals exactly what data is and how it is captured, stored, shared and made sense of. Fry also tells the story of the engineers of the data age, people most of us have never heard of despite the fact they brought about a technological and philosophical revolution.
For Hannah Fry, the joy of data is all about spotting patterns. She's Lecturer in the Mathematics of Cities at UCL as well as being the presenter of the BBC series Trainspotting Live and City in the Sky, and she sees data as the essential bridge between two universes - the tangible, noisy, messy world that we see and experience, and the clean, ordered, elegant world of maths, where everything can be captured beautifully with equations.
Along the way the film reveals the connection between Scrabble scores and online movie streaming, explains why a herd of Wiltshire dairy cows are wearing pedometers, and uncovers the remarkable network map of Wikipedia. What's the mystery link between 'marmalade' and 'One Direction'?
The Joy of Data also hails the giant contribution of Claude Shannon, the American mathematician and electrical engineer who, in an attempt to solve the problem of noisy telephone lines, devised a way to digitise all information. It was Shannon, father of the 'bit', who singlehandedly launched the 'information age'. Meanwhile, the green lawns of Britain's National Physical Laboratory host a race between its young apprentices in order to demonstrate how and why data moves quickly and successfully around modern data networks. It's all thanks to the brilliant technique first invented there in the 1960s by Welshman Donald Davies - packet switching - without which there would be no internet as we know it.
But what of the future, big data and artificial intelligence? Should we be worried by the pace of change, and what our own data could and should be used for? Ultimately, Fry concludes, data has empowered all of us. We must have machines at our side if we're to find patterns in the modern-day data deluge. But, Fry believes, regardless of AI and machine learning, it will always take us to find the meaning in them.
画面挺电影感的，配乐也挺吓人。一颗隐约的头，朦朦胧胧的，真的是永不过时的惊悚画面呀～
影片大体上中规中矩，这个故事还是比较普通的，就是一个变态窥探+杀人狂跟女主斗智斗勇的故事，剧情的紧张惊悚氛围比较低，偏于平淡，节奏偏慢，也没有反转；不过有一个大的问题，就是女主最后被割喉后，那出血量未免太多了些，床上/衣服上/地上都是血，何况地上还淌了一大摊，即使不死也应该陷于昏迷状态才对，可最后女主竟然站起来，去摸了枪再走到门口打死凶手，这体力真不是一般的强，平时也没看看见女主锻炼身体啊！如果没有这个问题，我会给6.3分，现在只能给3星5.9分，删掉！
地铁那段戏一度我都快要以为偷窥者才是女主的灵魂伴侣的时候，被塑料袋里的玩意吓死了
压抑的气氛做的很棒；专注了被凝视的感觉，其他的都被弱化了；这一枪太假了，如果女主挂了好一些，这样为了爽而爽反而不好；摄影可以更好点？

很不错！国内也可以多一点这种套路的恐怖片，建国后不许成精，所以拍更吓人的偷窥跟踪男和连环男杀手吧。
非常中规中矩。我觉得应该谢谢契诃夫——第一幕出现了手枪意味着………
闷。心理元素运用的可以，总体还是比偷窥者要高级
希区柯克式悬疑。很常规的拍摄，题材，设定。
烂得很全面。本意大概是要反映她对于隐藏的连环杀人犯的第六感，然而在突兀的最后一个镜头，就会猛然醒悟到她时时刻刻携带着枪支，跟持刀的凶手不在一个层面。而且，脖子被抹一刀，还能站起来从背后亲手毙了凶手，那么前面的神经兮兮是装给谁看的？凶手以前作案都是割掉被害人的脑袋，为什么对她就只满足于放点血？女主角一副苦瓜脸，言行从一开始就让人厌烦；凶手一脸死相，就差没把字写到脸上；拍摄手法极其平庸，毫无氛围；被监视这一点没有花心思去展现。凶手除害失败，哪里有什么惊悚或恐怖。[ZXZJ]

同比偷窥者的话，其实挺差的 为了时长也增加了丈夫陪同打消顾虑的戏份（但是这种对于女性的社会伤害，还是很需要消除的）
半夜看了睡不着。男主那嘴巴，一看就不是善茬。
如果你感觉被监视了，就一定被监视了；如果你的小区里有人被杀了，那么一定有人想杀你；如果你向丈夫解释了，那么他一定不会相信；如果你报警了，那警察一定没用；如果有人监视你，那他一定要杀你；但如果你是女的，即使被砍了脖筋也可以击毙歹徒。用多个弱联系强行构建想要的结果，典型的滑坡谬误电影。
氛围营造很是到位，同为女性太能感同身受，电影院那段身后的椅子细碎声以及超市那段货架间的行走，电梯下行女主与反派的对视，代入设想一整个要窒息。后段寂静的地铁廊道下一刻地铁进站的声效成功达成听觉版的jump scare，但结局不太好，反杀还是要干脆利落且符合逻辑才能让观众信服，被割喉还能站起精准开枪还走那么远，既然要完成反杀设定不如在爬行且反派被对面小女孩吸引视线时完成还更流畅些…以及要这种不相信自己妻子还能拿妻子的被跟踪开玩笑的憨憨丈夫有何用？
女主有点奇怪，又害怕又胆大，看不懂。
not bad 男的是不可能和你共情的（夸张但没夸张
Sundance genre film always much fun
结尾像是导演怕观众说女主被害妄想症而强加上去的
不要一厢情愿度测一个女人的说法……
