Reasonably entertaining if you can overlook some plot developments

Rating: 6/10 (15 October 2013)

It takes about half an hour plus before something interesting or worth exploring further comes up. However, the visuals are indeed beautiful - the futuristic white station built atop a mountain, the well-designed swimming pool, the mountain peak where Jack sat on and did things like watering a small flowering plant grown in a can as he looked upon the gigantic hydro rigs and the surrounding landscape.
There are a few plot twists, but most of them turned out to be not very interesting when fully revealed. The real identity of the scavengers and the appearance of Jack's look-alike drone maintenance man did surprise me a little, but that's about it.
The ending may appear to be slightly rushed, but it would somewhat satisfy those who would like to see a 'complete alien destruction' ending.
Reasonably entertaining overall, but I won't recommend that you buy its DVD or Blu-ray disc unless you are totally alright with the perceived lack of character development and average storyline.
