It's pretty bad when the best acting comes from...
...those robotic-like children.
They were actually quite good...the rest of the cast was HORRIBLE!
As for the movie, it had an interesting, unique premise...but didn't go anywhere. They could have done so much more with it.
As for the ending, it's a joke...and it comes far too abruptly.
They traded God's truth for lies and worshipped/served the creation rather than the Creator.
