Characters were all off

Rating: 1/10 (1 June 2016)

The movie has visuals going for it, as well as a setting that COULD have been used to make a good movie. This is why it is so frustrating it turned out so badly.
Worst of all are the characters. None of them make any sense.
The robot is experimenting on important crew members for no apparent reason. If he had picked one of the presumably expendable people with no name that are on the ship it would make a little sense. As for the first experiment - infecting Halloway, by making him drink alien goo - he doesn't even seem to care what the goo does to him, but looses interest in him. When he discover Halloway's girlfriend is impregnated by an alien embryo, he again for no clear reason decides to sacrifice her and keep the embryo. But when she manages to get the embryo-now-baby-monster, he simply doesn't care, and never inquires whatever happened to the embryo that was important enough to him to kill for. The baby is alive and well where he was left, but he never even goes into the room to bother to see if it's there.
His actions seem more like a sick person playing tricks on people because he is bored, and who moves on to something new when the trick is finished.
The biologist and geologist also just seem crazy. They freak out for no reason and leave their team - supposedly you would pick more cool headed people for such missions. After that the geologist forgets he is the map expert and has a 3D map, and the biologist tries to pet an alien snake and gets killed.
Weyland, the rich man funding everything, hides for no reason in the ship. There is no rational explanation why he keeps it a secret he is on the ship. I am assuming he is paranoid that someone will kill him for no reason, or maybe he just likes to surprise people?
Shaw seemingly forgets everything instantly. Her husband is out of her mind as soon as he is dead, and she never mentions to anybody that she just removed an alien embryo from her body. The only thing she remembers is her Cristian cross.
Vickers seem like an aggressive sociopath, with no plan and nothing in particular she wants out of the whole space travel project, except bullying her crew mates.
The two co-pilots seem strange and sort of sedated. They don't even react more vividly to being blown up for no reason.
The captain is the only character that is believable and at least seem like a normal human being.
The movie doesn't make sense having characters as these, as they are supposed to be an elite team of top scientists. The movie would have worked if they had adopted the "Dirty Dozen" plot, that mental patients and convicts get a chance to get a clean slate of they volunteer for a suicide mission in space. Alternatively, this could be an internal plot in Weiland's company - his colleagues want to kill him, so they manage to get him the worst crew they possibly can, to ensure he never returns from his mission. This would have made the movie work better, it would at one stroke have explained most of the erratic behaviour of the characters, and it would have been a chilling background story. As it is, it simply does not make any sense.
