Recently many sports games have had very dramatic results. Often we don't know who the winner is until the very last minute, which drives the audience crazy. I totally agree with the opinion that we cannot predict the winner of the competition until the last minute, so if we continue to watch until the very end, an unexpected result may still occur.
In real life, many times thing happen in an even more dramatic manner than of the movie world. The saying "life is like drama" probably is referring to this situation.
