Could have been a classic movie

Rating: 3/10 (4 June 2012)

Spoilers ahead:
The good first - excellent visuals and direction/production.
The bad - very poor script
I went into this movie without any expectations. I did not expect this to be a prequel to alien and I deliberately avoided the trailers.
I left the movie very disappointed though as the film's potential was not reached. There was very little tension or horror present. A lot of characters die but you will not care as you do not get to know them. A lot of characters act irrationally - poor/absent decontamination procedures. Or opening the doors of the ship to a crew member who has died within the dome with acid eating up his face and has his legs bents over his spine. Would you open the door?
I know most people will have read reviews with the plot so I will not go into it. Instead I will highlight some of the many plot holes found in this movie.
1. The spaceship approaches the planet and finds the exact place where the dome is. 2. The lead scientist takes off his helmet despite the unknown risks of airborne contaminants in an unknown planet 3. 2 people get spooked by an alien body present and tell everyone they are heading back to the ship 4. They get lost within the dome despite the dome being mapped earlier by robotic 'pups'. 5. They then return to the same place with the alien and try to befriend ( 3 times) an alien cobra/worm that pops out of some black goo. They die. 6. Woman who should be quarantined escapes without anyone looking for her. 7. She then has surgery to remove an alien from her stomach and then manages to run around afterwards. 8. She is half naked covered in blood with staples in her stomach yet no-one appears to notice. 9. Why does the woman want to go to the Engineer's home planet after one Engineer killed most of the crew and almost killed her? It's doubtful that she will be welcomed with open arms.
I could go and on but to be honest I can't be bothered.
