Bad Graphics are if, for it's time, the game lacks the technical specs that can be expected for the period while at the same time not adding anything to the art style. A Shooter that is supposed to be realistic but has huge pixels and fuzzy textures has bad graphics. Minecraft benefits from specifically having very little detail, so I can't say it has bad Graphics. And a game that was gorgeous in 2001, but no longer stands up to the competition, doesn't have Bad graphics because it just reflects the time. Graphics are a fine and dandy thing to have, and good graphics are laudable, but they also are not as important as, and easilly forgotten in the face of, good art direction.
