Staff over at The A.V. Club discuss the plot devices and mistakes that take you out of a film’s story. I chuckled at this choice by Marah Eakin:
Mine’s super-petty, but here it is: I hate when a character drinks from or carelessly wields a clearly empty “hot” coffee cup in a movie or TV show. Most people would just be a little annoyed by this, but it makes me question the whole production. Couldn’t they bother to put some water in those cups? And if they aren’t paying attention to even middling details like that, then what else did they ignore? Are the characters developed? Are the sets how they should be? Did they edit the whole thing together well?
