"Creo que cuando tienes que hacer 20 tomas para una escena, se vuelve un poco gratuito."

Simplified Meaning:

When someone says that doing 20 takes for a scene is too much, they mean it's becoming excessive and unnecessary. Imagine you are making a short video with your friends. If you have to repeat the same scene 20 times, it can get tiring and frustrating. At some point, repeating it again and again doesn't make it better; it just wastes time and energy. For example, think about practicing for a school play. Practicing your lines a few times helps you remember them, but if your teacher makes you practice the same scene over and over for hours, it can become boring and unproductive. You start to lose enthusiasm and might perform worse instead of improving. In life, it's important to know when to stop and move on. Whether you’re doing a task or learning something new, don't get stuck doing the same thing too many times. Find a balance – practice enough to improve, but not so much that it becomes pointless.
