The final scene (before the credits) is a direct homage to American Psycho and the scene of Patrick Bateman killing his coworker. Eddie plays an 80's tune and dances to it while his room is covered in newspapers (just like Bateman's) and kills the crew.
As the film progresses, it's revealed that this takes place in the Marvel universe and a twisted version of it at that. Newspaper clippings are spread out each giving more information to the time and the character of Eddie. It's in the climax that it's revealed the camera crew had following around Eddie Brock of all people, also known as the cannibalistic Spider-Man villain with an alien suit called Venom, and he's led them to his place of feasting.
Despite it being based on a Spider-Man character, the web-slinger only appears in brief conversations and newspaper clippings sprinkled throughout.
