The film is easy to follow and understand, not overly cerebral with techno jargon. The effects are very realistic and indeed give the viewer a sense of the realities of space.
The story however, is extremely weak and anticlimactic. It lacks suspense and excitement, anticipation and emotion. It is one of those movies I regret watching, for the time I wasted watching it. As a possible docudrama, I could appreciate this more. But as a movie, it was woefully inadequate and disappointing.
