Believe me the plot is not what's bad. If you read the Grimoire and decifer all the damn riddles, and have some knowledge of quantum physics, particle physics, Greek mythology, Nordic mythology, some biblical references, then you can respect the story Bungie made, but seriously who is knowledgeable in all those topics? Kinda asking alot of a bunch of gamers. Plus they also did a bad job of giving us the story through the game. They probably learned and should make better experience from here on out.
