My comment was from the view point of the creators (director, writer, and rest of the crew). There were better ways to make money in movies in 2007 then with a sci-fi space thriller inspired by Solaris and Alien.
To be more clear, I don't think the creators were thinking "will this scene make us more money", nor do I think it's their job. And on the topic of realism in a movie, unless it's a historical film or the goal is to educate, then realism should be near the bottom of the checklist when creating a scene.
