There are plenty of talented writers and directors with original ideas. Imagine you are an executive of a major studio and you have two pitches: one is a really fascinating idea for an original action-adventure film and the other is for a reboot. Both pictures require a budget over $100 million. Market research has shown you that you are guaranteed to break-even on the reboot, but because the other idea is original, no market research is available. It could flop and you lose $50 million dollars, or it could do really well and you make lots of money, or it could fall somewhere in the middle. You would take the guarantee, because at the end of the day, you are a business and your bottom line is what matters most.
