I thoroughly enjoyed the movie, although I had two problems with it; one that I typically do with sci-fi movies and the other with other people's characterization of some of the characters.
First, I fucking hate the scientists in sci-fi movies. They're always just so retarded and dismissive of genuine concerns. Even in instances where they're supposed to be the good guy. Not just the biologist
It's this attitude of "we have to know" that just grinds me. I'm more the kind of guy that takes David's position: "Why do you have to know?" To me that was easily the most thought-provoking question in the whole movie, and then it just gets blown off with a retarded, "Because...I'm a human, you wouldn't understand."
The second problem I had was Charlize and Michael Fassbender's characterization by some as bad guys. But they never really seemed like that.

randomly deciding to pet an alien life-form, whose physiology he's clueless about, but even Elizabeth's plan at the end: Hey, those aliens really hate us and want to kill us. I better go to their home-freaking planet and ask them. Honestly, if the sequel is just 5 minutes of her walking up to an alien all indignantly and asking, "Why do you hate us?" before getting her head ripped off, I'd still buy a ticket.

Charlize always acted in the best interests of the majority, especially when the boyfriend was infected. Fuckin' right you don't just let someone on board with an unknown ailment that's wrecking his shit. And as for the "ulterior motives", she never had any. Her father had the other motives, and she was pretty opposed to his decision. And Michael, he never really did anything unsavory. Even the poisoning of the boyfriend, he only did it after the guy said, "I'd do anything for this mission." The robot just took that shit literally. The specimen in Elizabeth was just an unintended consequence. It wasn't that he was evil, it was more that he was a child who was curious about everything.
