What a waste. I'm a sci-fi fan and even I give this movie only a "6."

A lot of talented actors, quality sound & cinematography, but the screenplay really doesn't hold up.

In addition to being too far-flung in the number of principal characters, it's too long, and becomes almost comical at times in its plot twists.

The movie would have been better served to have: - limit principal characters/stories and provide greater depth for remaining ones - Make the earth-related issues more believable

Your time is better spent on a lot of other, higher-quality, sci-fi movies.
