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.
作为从小看《铁道游击队》长大的山东人，这部电影看得人心潮澎湃。张涵予和范伟的演技一如既往地很稳，让我意外的是几位偶像转型的演员演技也让人眼前一亮。当然，这部电影的意义远比电影本身来得要大，“珍惜前辈们用血肉换来的和平生活”才是它带给我们的真正思考。
基本等价于《革命者》2.0，摄影、特效、音效、美术都更好，剧本则更烂。光注重视听塑造了，剧本一盘散沙，叙事节奏非常拖沓。范伟演的在他的水准内，但人设和《长津湖》的胡军太类似。全片一到关键时刻就上演死亡催泪大法，导演的招数少的可怜。
看预告片时候美术服化道是最大优点。谍战戏无聊，没有铺垫突然就有出现一个汉奸，人物的行为逻辑动机很难成立，背影音乐插入很刻意，感受不到情绪难以共鸣。
国外版坏人变老了。这老太太逻辑招人恨啊。最后被汽车压头都没解恨哇。老太太散弹枪打小女魔头被后坐力弹出去比较真实。
人物塑造还行，人物感情基本没有，英雄气概也没表现出来。色调本来是我喜欢的，但是导演这拍法我确实有点看不懂，感觉无聊
中规中矩的主旋律，但是玻璃上画党旗那一幕也算是革命浪漫主义的体现了，眼前一亮！
20220110le。范伟真是个难得的好演员啊。和他对戏的那小伙子也不错。
作为谍战片 前戏过长、节奏偏闷。
除了海报上的两位主角，其他的人物确实有点薄弱，但影片的年代感和氛围也确实营造得不错，抗日英雄的血泪事迹很感人，却不煽情。
即使用质感画面和演技也不能掩盖的主角光环和抗日神剧本质
如果主旋律都是这个制作水准的话我还是很愿意买单的 摄影美术都很在线 也终于有国产商业片不用台词用镜头讲故事了！ 张涵予的硬汉形象比战狼帅多了 就连反派都那么有漫画感 （本来战争片就不要一味地矮化敌人嘛！斗智斗勇才好看）该死，被装到了！

略显失望，故事本来有个很好的根基在，可惜导演水平不够，所有的事情都做得太行货，太平庸，前面觉得某些氛围的营造还是可以的，到总体节奏失衡，单有氛围就容易故弄玄虚，观众对这样的故事已经很熟悉，而剧本的处理还一直顺拐，所有情节都做得理所当然毫无悬念，演员阵容不错，两位主演也很卖力，可惜缺少细节，导致人物塑造留于表面，很难引起观众的共鸣，而且最让我出戏的是高潮戏有些连动作都不接，明显缺了镜头吧。7
【6.5-】年轻人的性爱是黄片，那老年人的性爱就是恐怖片，不过无论是何者，都会被归类为X片。前后类型的反差也代表了不同欲望在不同年龄段带来的不同反馈。由同一演员饰演的老太太与女主是处于不同时间段的一体两面。不过就如同年轻人与老年人身体素质的差距一样，前面氛围有多棒，后面就有多泄气。
合格的爽片，令人动容的地方有三处，一是在窗户上画党旗宣誓，二是范伟被抓上火车，三是张涵予杀身成仁，除此之外本片依旧脱离不了“神片”的范畴，看完基本没啥教育意义，只记得散场的时候我身后一对小情侣中的女孩说了句：我现在就想拿把机关枪冲到日本去。
爱国热血！
魏晨台词不太行啊
范伟老师的老王是整部影片中最饱满的角色，而张涵予的角色过于程序化，女护士的角色简直可以省略。铁道英雄值得称颂，但是这部影片只是还行。
范伟不错，故事不行，动作夸张，反派设计太弱智……
就是很纯粹的不好看，导演编剧都有问题。节奏拖沓，漏洞不少，揉了不少谍照元素进去也只流于表面，反倒是最重要的劫火车这件事既不紧张刺激又缺乏战术配合拍得非常糟糕。张涵予完全沦为工具人，白瞎了范伟老师的好演技。
