Disappointing if you are expecting "Aliens". There are no xenomorphs, facehuggers, or eggs in this film.
Plot is okay, and special effects are great.
1) The characters are stupid, and entirely forgettable. After about 2 minutes of listening to anything they say, there will be no mystery as to why the Engineers want to kill off all of humanity.
2) The movie is slow,...you will spend far more time waiting for what is next to happen, than actually viewing it.
3) Huge plot holes. Why would the Engineer Aliens leave ancient clues on Earth directing man-kind to a planet that as been setup as staging area for an attack to wipe out humans? Why was Charlez Thereons character portrayed as villian? Why did the android want to impregante boring-female-main-character with an alien?
