SamRag Well, maybe you have to be a bit of sci-fi fan, or maybe just enjoy the challenge - or maybe just even be in the right mood. For what ever reason, I enjoyed this movie a lot. It had some of the challenging thoughts of 2001 (a movie I appreciate but do not enjoy at all), while at the same time trying maybe a tad to much to be like The Martian at times. But it worked. It left me thinking how much we really do not know. How fragile we just might be in space travels, while at the same time the stubbornness and geniality of our species might just see us through.It might also have helped that Mark Strong is one of my favourite actors. I was raised in the theatre, and this movie is perfect for the stage. I haven't checked it - but it just feels like a screenplay for theatre. There he would be speaking to the audience, but the thrill and the angst would translate so well.What would I have done differently? I would have reduced the 2001 scenes, and the Matt Damon voice over a bit. I might have put a tiny bit more of reasons (or lack there of) of friendship and tension with the two other main characters. Bottom line - this is not a 5 star movie! It is not a blockbuster, or big budget movie, but a very very well done set piece of a movie, that deserves at least 7 to 8 stars! See it, and let us know!

Daggyy There are a lot of people saying this movie is absolute garbage. And I can understand that some, or many, people might feel they just wasted their time. For it is a slow movie, and there are very few actual happenings. But this is a psychological movie, more so a thriller than anything else. The film didn't need any more character development or action, as it was just supposed to be a relatively short movie with just the bare minimum of most devices. It shows us what we need to know (SPOILERS): A desperate man on a mission to experience something new. He knows what is on Earth, and wants one moment of pure wonder as he ventures into space and eventually Mars. Furthermore, he is actually psychotic in this need to experience, as he completely disregards Houston's orders and his friend Skinny's advice and efforts to help when his water generator breaks. He was, however, scared to be completely alone, like he will be since his colleague Maddox had to turn around. The movie ends abruptly, and we have no idea on whether he can fix his water supply or if he will just wither away and die.

davidmcardoso You probably have already seen in other sci-fi movies with great plots which astronauts are headed to Mars, however that's not what's going to happen here. Probably director's intention was to let us know how boring a journey like this might be and no doubt its goal has been achieved.

GreenBottles The main character correctly asserted that there is more space between our atoms than mass... coincidentally there was more space in this movie than plot. The interest in Sci-fi lately has been boosted by realistic and scientifically based premises, even if somewhat stretched. This movie lacks any credibility.
