So movies shouldn't break the laws of physics?

The article "So movies shouldn't break the laws of physics? Don't tell Captain Kirk" is written on a view of someone that takes in every single detail of every single moment of movies. Though Sidney ­Perkowitz says that "The main idea is to limit films to one transgression of the laws of physics each (on screen only, otherwise they'd all go for perpetual motion machines to power the lights). Presumably this is in addition to the one coincidence to which good screenplays are supposed to be restricted." it doesn't always have to apply. I mean seriously how many professional Physics and scientist are there? They aren't a very huge population out of the 6 billion people alive on earth. To these you can include film makers, producers, screen writers, etc. Even though there a population of these workers it doesn't eman that everyone in the whole world or even everyone who is going to go see these movies are thinking like them or even just going to see if the cigarette is at the same length as the last time it was shown or if the hair of the actor is more wet in one scene or the other. NEWS FLASH: People don't really go to the movies to make sure everything is how its supposed to be, to see if every single frame shot is the same as the last or even if what they are seeing actually happens in real life. The audience doesn't really think " Gee when a space ship explodes in space does it really sound?" They are to into the movie to stop and notice that. If an object like the cigarette is noticeably larger or smaller than it was a few seconds before then some audience members are bound to see the difference but they don't really care, they are too preoccupied with whats going to happen with the main characters, will they die or will they reunite and realize their love for each other. So honestly though a movie does have to be organized enough so that people like it and watch it,it doesn't have to have a set of rules, every movie if different than the one before it or after it.
