Watched the new Luther episode today and there is a scene where Loofa yells that he can't possibly pick the padlock because it's pick resistant ... but I have taken up lockpicking as a hobby, and one of the easy peasy can't possibly fail locks is the Masterlock M3 - which is what was on screen. A character who carries lockpicks with them regularly should have been able to pick it faster than the director could say "cut"
As a computery person I feel 99.99% of everything ever said about computers in all TV/Film/Books is written by people who don't know what a computer is, what it's for or why you might use one... however, now that I've spent a few years with computer students I've realised that lots of people who should know these things don't so I feel less animosity to such things.
More specifically as a hackist - oh god no, it's never right (Notable exception would be Mr. Robot and even then not always perfect, or the beginning of Sneakers)
What things do other people know that make you cringe in movies and TV because you know it's BS?
