As a hard science fiction style movie this was actually pretty well put together. Bear in mind that it is presented in a realistic on board style video camera style from various points around the ship. This style can take a little getting used to but it eventually you can get used to it and it felt it had some difficulty in editing at some points.
The minor downside is the difficulty of how realistic the procedural aspect is presented. Would a real mission behave like this? I guess to add to the drama perhaps that was the point.
I did like the outside the space craft shots with the lack of stars and realistic contrast. I was not entirely sure about the rate of rotation of the space craft but I did like the concept and acknowledgement of issues of radiation too. Some pretty good science references through out.
