After watching S01 I can say it has interesting moments, especially the horror episode (was it 05?) and great end-of-the-world atmosphere but there is too much emotional navel-gazing, especially the Japanese girl's grief is overdone. This emotional soap opera dominates the plot, and is tiresome, the girl has the same sad look, the mom looks awestruck and overwhelmed with her mouth open most of the time and the soldier also has one expression on his face throughout most of the series.
The aliens are somewhere in the background, we learn about them next to nothing. They seem menacing but their demise is too easy, all of them die instantaneously and we don't know exactly what (and how) caused it.
Some of the first episodes and the last one seem redundant.
Why do they introduce Sam Neil's character and drop it in episodes 03 or 04?
And science in the show is treated really badly. I couldnt understand what really was going on with the space station, and how they tried to communicate with it. Why did the rock kill the aliens? Plus, the idea that an astronaut can move in space by 'swimming'...
Too much focus on emotions and too little on plot and the aliens.
