I have to admit, after watching the 1960 version, also based on the same source, this was a breath of fresh air! No pun intended, although air itself is not really a problem here. Staying sane on the other hand ... that is an issue.
If you take on a trip, you plan on how long you'll be away and when you'll be back. Even if you plan that there may be complications, you could not calculate what happens here. And while you may wonder and think about science - I would advise you not too! Because the movie itself is above that and cares more about the humans and what happens to them. Now it could be displayed a bit better, there always could also be more enticing and gripping depictions of individuals ... but as it is, the movie is more than able to give us the fear and terror, while trying to stay optimistic and sane at the same time.
The pacing may be a problem with some, but it is quite the update to the 1960 version! Of course they had more money here, technology improved and so much more. This also is way more explicit when it comes to nudity and sexuality. Obviously something that could not have been done in the 60s. If you like Science Fiction that gives you food for thought (again no pun intended), this may be for you. As I said on the other movie, I have not read the source this is based on.
