...A.K.A. Movie cliches that totally annoy you.
The Wilhelm Scream - okay, this one doesn't annoy me. In fact, I'm actually a fan of it and will employ it in all of my movies I make in the future somehow.
Thunder occurs the same time as lightning - This one totally annoys me. There's no explanation for it what so ever. The thunderstorm sounds just as intense with or without the delay in between.
And the one that annoys me the most - Mom prepares a breakfast for the family, usually consisting of the stereotypical breakfast-y foods, eggs, bacon, toast, pancakes, etc. Dad and the kids will arrive at the table 30 seconds before they have to head to work and leave for the school bus. Each will only have time for a sip of coffee/juice or a bit from a piece of toast, etc. Dad gets a kiss goodbye from mom and has his suitcase and stuff and heads to the car. The bus is waiting outside for the kids and always honks its horn for them. When they all leave mom is stuck at home with enough food to feed a third world country. I gotta give Forrest Gump credit. He had his kid ready for school early AND waited for the bus outside with him!
