Based on a true story ?
We often watch movies and other kind of tv shows where they tell us that's based on a true story. When you dig deaper in such stories you understand that's not completely true. They always add things or remove them. Show us what they want us to see. Maybe the whole story is not true sometimes.
I mean that we shouldn't trust any movie completly that what's going on was true. It's all a show for people and they write that's based on a true story just to make us trust them.
After all even the history can be edited. We never know if something was true or not unless we saw that by ourselves.
