Spacejacked

This movie was really the worst I've ever seen! The scenery was terrible, you noticed they just used two elements while creating it: plastics and paper. The storyline was just weird, not to mention the many logical mistakes they made... How can the two guys speak when there's a vacuum? Why does the good guy not kill the bad guy, but instead just make him unconscious and lay him directly next to his laser-phaser-hyper-blaster-cannon-gun? Why is the android smoking? Why is the android smoking a cigarette? Why is the android laughing? Why is the android playing around on his chair? Why does the bad guy immediately kill Gibson after he gave him the "code" instead of let him alive and say he'll verify it and when its wrong he'd kill his wife? Why is quantum-physics (artificial gravity!) more advanced than artificial intelligence (android needs this earclip instead of recognizing the faces)? Just one more question: Why would anyone spend money on such a BAD movie?
