It leads me a lot of thinking afterward

Rating: 8/10 (21 June 2012)

At the very beginning, I have no idea what is going on, what does it do for the strong guy drinking the thing. At the end, I kinda understand why he has to do that, but there is no clue about WHY he/they do such harmful things to others, and that definitely leaves me a lot of thinking.
Overall the plot is good. The beginning is a bit long just to introduce how they come up with the ideas, the rest is quite exciting.
A few glitches, one is the standard of breeding aliens Second, can aliens still grow even without human flesh. Third, why cant the strong guys leave the planet
