I wanted to like this, but... woof.
I love games with a good, intricate backstory, and think it's great when they branch out into other forms of media to expand the story. I've never played Dead Space, so this time I'm coming at it from the perspective of someone starting with the movie, and I've just gotta say, it's got some hefty problems that really turned me off.
First, I don't know if it was the director's choice, the voice actors, or the script, but everyone was continually shouting their lines like angry, petulant teenagers, even when it was just normal conversational dialogue. The dialogue itself was incredibly immature and illogical most of the time. People just don't talk that way, not to mention professionals on a ship talking snidely to superiors and questioning or arguing over ever order (and this is long before the "madness" begins). It just smacked of someone who didn't know how normal adults, much less a crew, talks.
Secondly, the actions of the crew, and especially our heroine, seemed to be almost random, and ill-conceived, jumping from situation/knee-jerk response to same, again and again. The head of security didn't have set reactions or countermeasures to an incursion, nor was she taken seriously about her concerns, and her team didn't act like a trained security team, more like a bunch of yahoos with guns. And when she sees a threat, identifies the threat's strengths and weeknesses (from the initial encounter), she then proceeds to walk right into a gang of them and get most of her team killed instead of doing any logical preparation or utilizing the slightest hint of tactics. Ludicrous. (She also didn't seem to be very familiar with her own ship, which I found odd.)
Third, I'm at a loss as to understand why she had to use the shuttle to fire off the beacon and open the bay doors for venting, when A) she'd recorded the message with the bay computer, and: B) the ship shouldn't have control of the bay doors anyway. That's not only something the main ship should control, but didn't we also just see, at the beginning, that the shuttle almost didn't make it on the ship because the doors were being closed? (I don't recall the pilot ever grinning and thinking, "well, duh, I'll just open them myself. No hurries...")
And she was pretty quick to get herself killed when she very likely could have survived and continued trying to find a way to save any leftover survivors, something she certainly kept repeating to everyone else thoughout the movie as a priority. She didn't know whether everyone was dead or not (and according to someone else's post, there apparently are survivors around the ship that are discovered during the game).
And where the heck was the beacon with the warning message when the ship arrives in the end?
