Now - this is easily a 4 star film, but the DVD presentation means I can only give it a 3.
As another reviewer has said, the tickertape introductions to various scenes in the film are an integral part to the overall feel, to replace these with substandard ones feels nonsensical.
Anyway - the film is very slow paced, very different to contemporary Hollywood films with quick editing and catchy dialogue. The slow pace gives the film an added tension.
The sets are spectacular, everything feels real and solid, the idea of having to go through several hours of cleaning and sterilisation adds further to the realistic feel of the film. Some of the sterilisation processes were fantastical yet based to some extent in real science.
Speaking of real science - that's where this film excels. It somehow captures what a scenario like this might be like. Even down to the beurocracy, politics, and less than glamorous settings. There are lines in the film that aren't designed to be sound bites, or further the plot, they are there to represent the realities of human interaction.
This is a great film for any Sci-Fi fan.
