Great But Flawed But Still Great

Rating: 8/10 (15 September 2012)

This review is only for those who have watched the movie. On second thought, this is not really a review but a post on the flaws I've seen on the movie.
So what are the flaws? When Noomi (dunno the name of the characters) got pregnant with that alien thingy, she did a surgery to take it out. She was successful and after that, nothing more on that "creature" was seen again until the final scenes of the movie. Fast forward to the final minutes, the creature was ALREADY BIG. I assume it became an adult or something like already. My question now is how did it became like that? I doubt that creature can just become that big without consuming anything. Well, let's just assume the creature managed to eat one of the crews. End of discussion.
The second flaw is the fact that it seems like crashing their ship, Prometheus, to the alien ship is the only way to stop the latter, that is, the alien ship. Yes, that ship might have been a cargo or a travel ship and that there's no weapon in it. But why crash it? They could have raced with that alien ship to earth. It was never showed as to how fast both ships can travel so crashing the one to the other is just a big flaw for me. Another thing is that the movie took place in 2080+. Technology prospers. I know NASA or a government agency would have detected any alien ship coming towards earth. So why crash Prometheus? That's all thank you. XD
