Haven't Seen the Alien Movies, Still Know This Doesn't Live Up to Them

Rating: 3/10 (21 March 2015)

This movie is filled with characters I don't really care for - besides David, who is a twisted cyborg - who come up with conclusions with little evidence. For example, after the opening of the film Noomi Rapace looks at cave drawings of a man and what appear to be UFO's, to which she just assumes "I think they want us to come find them."
Thus begins a journey for her and a full crew to "meet their makers." This corresponds with the opening of the film where what looks like a gray-skinned super human who drinks something which causes him to disintegrate, and once his matter is in the water it reforms into DNA, which is when we see the title "Prometheus."
Unnecessary aspects of this movie: Guy Pearce did not have to play an old man in crappy makeup - they could have just hired an older actor. There is dispute whether or not Charlize Theron's character is a robot, which she clearly isn't. Also, she's pretty much in the movie to be a b**** and to show her stupidity in not knowing how to run adjacent to a giant ship about to crush her instead of in a straight line which the circular ship follows.
So at one point they end up "meeting their makers" as they believe them to be, but what pisses me off is that the "engineer" simply rips David's head off of his body and attacks the others. Noomi Rapace wants to know why their makers hate them, and so do I, but if they are displeased, why follow their path into a sequel? Wouldn't they just want to kill humans like the one in this movie clearly did?
I can see why they avoided saying this was a prequel to Alien - it hardly deals with things I assume to come from those movies, but addresses it right before the credits. This could have been better if they decided to make a standalone film not connected to Alien AT ALL. There are actually plenty of ways this film could have been better.
