A mission to Europa goes awry. However scraps of video are recovered. The mission center recombines the scraps and extrapolates the results.
We get to see the results and help speculate.
First there are no Gabor sisters, big red spiders, or any fun stuff; at least not at first and maybe never. I guess there is no time for a love story unless it was love of a new planet (moon.)
Second they must have taken photo lessons from the "The Blair Witch Project" (1999). Sprinkled with lots of flashback, sound bites and other unnecessary garbled video.
Of course even though it seem slow (the first 20 minutes are like watching paint dry) eventually you will watch it in hopes that it at least will be "Ten Little Indians" by Agatha Christie, in space. You will not be wasting your time whether you watch or not.
