The movie is beyond any doubt well done. Well acted, beautiful images, script and direction are OK. And in ANY movie it is always a matter of tastes. So no review can ever be really objective. So, if you like introspective movies where the action stays in little things, where nothing particular happens, where the acting is everything and where there is not lot of social interaction, and if you liked Solaris, Europa Report, and Moon, then you will enjoy this film. If you are more like me, more for movies where there are many things happening, more than Sandra Bullok's worried face and "oh no, we are lost" for 90 minutes, then you may find this movie very well acted and quite boring.
