Dumb things just to make the movie work

If someone knows your every move, why the hell would you have no curtains on your windows? oh they had to have no curtains for this movie to work right?
Why would you just pat the dog and chat with those around you when you clearly have a time limit to save the dog?
I could go on and on...
Really dislike the kind of movies where they have to have stupid dumb things to make the movie work....
