8. Prometheus
The Hype: Ridley Scott, making his grand return to science fiction! A totally stacked cast, featuring Noomi Rapace, Michael Fassbender, Idris Elba, and Charlize Theron!
Gorgeous special effects! That amazing trailer! How could this go wrong?
The Reality: Well, by stringing it all together with a terrible script. Very few of the actions taken by any of the characters in this story make any sense, and it's all wrapped in philosophical claptrap that would embarrass a high school sophomore. Such a monumental waste of talent and possibility.
