I liked this much more that the earlier films. It humanised the characters much better than the previous two films and was not rushed in the way that both came across as being.
It had a few flaws. At the beginning of the film, where life is to be introduced to Earth, you see plant life in the background. Also, thanks to evolution, we would have evolved to look like our masters on a planet of such genetic diversity. Idris Elba would have been better served having a British accent and the Silica storms that occurred would have caused a lot more weathering to the structure which was investigated.
If you like science fiction and/or horror, this is certainly worth watching.
