7. Digital Projection
Back in the day, cinemas needed a projectionist who knew how to load a film reel and then project it in the proper way. With the revolution of digital projection, that has gone completely out the window; all they need to be able to do is open a package, plug a hard drive into the cinema system, and then extract the digital files from the hard drive with the relevant password. The fundamental difference is that an analogue projectionist will have been trained extensively in the skill, even the art of assembling and exhibiting a film, whereas digital projection can be done near enough by anyone with a cursory knowledge of using a computer. The result is that digital projection tends to result in far more incorrect projections, be it improper framing or aspect ratios, and silly mistakes like passwords not being sent in time to unlock the package (as has happened to me at a few press screenings). Hell, there's even a famous story of The Avengers getting deleted ahead of a press screening, and the projectionist had to re-download the entire film again, which took around 2 hours. The potential for a jackass projectionist to ruin your night out at an awesome movie is too damn high!
