Europa Report is told primarily through cameras mounted throughout the spaceship, and secondarily through fake news footage and interviews from after the completion of the mission. This secondary footage taken from outside the space shuttle ruins the movie in two different ways. First, it pulls the audience out of the action. By giving us cinematic space outside the ship it provides a safe retreat for when emotions begin to run high, and in a movie that relies on the emotional impact of the death of its crew this ought to be avoided at all costs. The success of movies like Alien stems from the feeling of claustrophobia used to maintain their intensity, and cutting back to Earth just reminds the audience that the world doesn't end if this crew dies.
Second, it dumbs down the message. Take the movie's final moments for example: we watch as the one remaining member of the expedition sacrifices her life to capture footage of the alien life on Europa. Awesome, except then it cuts to an interview of someone telling us what this scene means. The last two minutes of the movie is an interview with one of the directors of the Europa program telling us things anyone who just watched the movie already knows. The crew sacrificed themselves in the name of science, their names will be remembered in the history books, typical sentimental shlock. How awesome would this movie have been if it ended with the mysterious single shot of the alien instead of repeatedly replaying the footage until it loses its impact? How great would this movie have been if it just made its point and ended instead of coming back and telling you what it was in case you missed it? Do you get it yet? Have I made my point? Just let the movie end.
(Unique story ultimately made average by its heavy-handed message.)
