6000 with an intriguing title and cover many people will see something interesting til they see the score and reviews. While having a setting that many can get behind, 6000 suffers from terrible pacing, lackluster characters, and an f-you author ending. The main redeeming factor comes from the art where the artist does a great job of manga's limited colors of black and white to create an atmosphere centered around lighting that makes this quick read at least nice to look at if you find a good source.

Overall, 6000 has plenty of problems while looking good. It's a short 22 chapters so it's entirely up to how you want to use your time.
