A fundamental requirement of cinema is that the audience suspends their sense of disbelief. Anything that breaks this will immediately has a negative impact upon the viewing experience. There are many things can severe this connection but the two most common seem to be obvious plot holes and Scooby Doo behaviour IE “Let’s split up…”. If these are the result of simply poor film making, then they can perhaps be forgiven. Every director has to learn their craft. However, if these two factors are present by design, then that is an unpardonable sin. Assuming that your audience is stupid, is insulting and the worse sort of hypocrisy.
