I found this to be very creative and it’s fairly cheap to make. The beauty about DIY videos like this is that when you see the possibilities of boosting your production value with minimal investment, your writing is impacted by it. You have an inch more creative freedom to invent a scene where rain could add to the emotion of the story. Maybe a kissing scene in the rain (how romantic), a body being dragged in the mud (how thrilling), or having the main character’s car have a flat tire in the middle of no where (can it get any worse, sure add rain).
