I cannot think of one single thing that I would change about this film. The acting is incomparable, the directing deft, and the writing poignantly brilliant.

All that we are seeing on the screen is happening with real people, real action sequences in the background, forcing the eye to watch as if we were there.

Just intense enough to provide a much-needed diversion, just lightweight enough to make you forget about it soon after it’s over. It’s not exactly “good,” per se, but it does what it sets out to do in terms of putting us on edge, which makes it … successful?

The story, direction, characters, and writing/dialogue is akin to taking a tranquilizer shot to the neck, but everything else was so well done.

but this time the setting is outdoor, on the brink of the soon-to-be-dried-up "dead sea". what we got here is a screenplay trying so hard to be philosophically deep yet at the same time totally clueless and pointless. the guy is what? looking for this mysterious woman, a missing person, for three years. when he first showed up, i bet 99.9% viewers would think that he was chased by a posse, a guy running away or escaping from a prison. the he ran up the mountain pass, found the woman who was loitering along the road. he claimed that he's been looking for her for three years and asking her to come back with him to some mysterious location to SAVE THE WORLD! yeah, right. then their conversation became so ambiguous and vague, like a see-saw or elastic band or even a bouncing ball, flying so high and so deep concerning human relationship, things evolved around during the three years time span, responsibility, world future, blah, blah and blah. the guy carried a long neck glass bottle of water and drank it during the conversation, and she licked and moisturized her lips and exclaimed: "you carried water? you drink water?". obviously she was also a bit thirsty, but the script did not arrange the man to offer her a sip of water. the world was definitely going to an end, it might be the Israelis and the Iranians would throw nuclear bombs to each other and the part of the middle east might be totally destroyed or whatever your imagination could carry you. but to me, this film is absolutely a going-nowhere one, also inevitably a box office nightmare. you guys could do whatever you like to prove that you are very deep and thoughtful, and you truly understand what these two only actors really tried to deliver, philosophical or metaphorical, deep or shallow, i just couldn't care less.

Apart from a couple of physics-related inaccuracies (which I'm sure will go unnoticed by the vast majority of people), a limited number of dialog imperfections, and a few lines where the heroine could've done better acting (voice-wise), this movie is BRILLIANT! Who would've thought you could watch two fellows talking for over an hour and enjoy every minute of it? Better yet, the developments and twists are cleverly woven in that when it all hits you in the end all you want to do is watch it again now that you know what you didn't know in the beginning. Not many movies do this to you these days.I have to say that I would've been seriously depressed if the movie didn't end the way it did. It was a huge relief, and joy, that such an exceptionally clever plot didn't blow it by a disappointingly stupid ending. I'm really looking forward to seeing more great movies from this new, yet not short of talented, director/writer. I think this movie shows that he's capable of producing potential Oscar-winning material.

I watched this film in Boston, and I can only say that the film is amazing, it's filled with surprises, at first i thought it's drama and has nothing to do with Sci-Fi, but then it proved to be the opposite, though the film only consists of two characters and one location but you won't get bored. This film may not be action packed or full of visual effects but it kept me watching and it is a must see for movie lovers or Sci-Fi geeks. It is so good to see a film that depends solely on story and dialogue, it's one of the most thoughtful Sci-Fi films ever made. The story is revealed slowly, minute by minute, but in a very mysterious and strange way.
