Why Natalie Portman got involved with this film is baffling. Maybe the idea sounded appealing: A mysterious 'Shimmer' appears at the site of a comet strike and everyone that gets sent in there fails to return except Natalie Portman's husband. He returns with a mystery illness and she, being a biologist is sent in to find out why. I won't say anymore about the story.

The film is just plain boring. The film makers don't seem sure whether they wanted to make a sci-fi action film or something more artsy. Instead they tried to make a combination of both, which, just doesn't work.

Normally, when films turn out bad actors claim they couldn't tell what the end product was going to look like. But Natalie Portman must have had an inkling when she was made to dance with an alien that looked like it had come from a 60s episode of Star Trek!
