Query: Horrible, horrible ending

At least two third of this movie is fun, teasing us with the prospects of an alien invasion and allowing us to imagine what is happening once a person is sucked by the light into an alien ship.But, lord in heaven, what were they thinking with the ending? Did they not do any audience testing? At the least, they could have left the conclusion open ended. Instead, we got the height of silliness.
