Kill a person, get 1 000 000 Dollars

"The Box" is a movie, that came out in 2009, starring Cameron Diaz and James Marsden. It takes place in the 70's and is basically about this box. The box contains a button and when you push that button, two things will happen:
1. A person, that you don't know, will die.
2. You will receive 1000000 dollars in cash.
Now what do you do?
I think the plot has so much potential, that it is rather sad to watch the movie evolve. All the sudden it is not about morality anymore but about some supernatural person, that likes to play around with people.

I rate this movie with 50/100, because the story could be really good, but unfortunately it is not.

Now, ask yourself: What would you do if somebody made that offer to you? Could you kill a person, even if you don't know that person? One million dollars is a lot of money, but is it worth the life of a human being?
