This was an interesting movie that can be summed up by a couple of its quotes:
"Maybe you'd be happy if you let people believe what they want to believe."
"What if there is nothing after this? No heaven, no hell. Just nothing. No awareness of the fact that we were ever aware at all."

I'm glad the movie posed these questions to the viewer because anyone who has ever considered their existence has probably found themselves asking them. I would like to point out that Jesus said that he was born and came into the world to testify to the truth. He came to answer these kinds of things. Yes, you might be happier if you let people believe what they want, but the right thing to do is tell them the truth. What we believe matters a lot more than short-term happiness. Also, Jesus said that there IS something after this life and he gave his life to deliver this message. If you got the message and believe it, you are the light of the world. Let your light shine before men, that they may see your good works and glorify your Father who is in heaven.
