Great movie. Thoroughly enjoyable!

Rating: 8/10 (1 April 2014)

I think most of the bad reviews are from people who've watched this in the theater. Because the movie has a slow pace. It's a much better movie when seen sitting on your couch at home. Or probably, because it was hyped by the marketing department! Also, I don't know if the guys who dwelled on the nitty-gritty science bits know this - Hollywood is in the business of entertainment, not in creating scientific TV shows!
Anyways, I really enjoyed the movie. Considering that it's just two characters, the movie was quite gripping. And also, I was full of awe seeing the inside of the space stations, the space walking, the dangers and sheer feeling of fear that if anything happens to you in space, there's no one to help you! The pictures of the earth with the clouds, the cyclones, the aurora was fascinating.
Wonderful entertainment. Really enjoyable.
