Injury, in addition to being a producer, Lindelof was the writer who was brought in to "fix" the script, because he's regarded as an edgy genius due to Lost, and Ridley Scott was worried that the script was too science fictiony (in the sense of serious science fiction like 2001 Space Odyssey). All of the shallow namedropping, empty ham-fisted attempts at metaphors and symbolism, incomprehensible character decisions, and goofy inexplicably absurd villainry can be attributable to him since it's the same shit we've seen his brain hatching since Lost. In the area of script writing blunders his wonderful contributions to Star Trek Into Darkness AKA The Wrath of Hannibal Cumberpatch Lecter Khan makes Prometheus look like Citizen Kane in comparison. I can't attest how he is as just a producer but it's clear he needs to stay out of the writing room.
