Awesome game to add to your collection.
The developers did a superb job telling the story and setting up a sequel( or side-quel is what I call it since it tells the story of Death during the events of Darksiders one) Overall I'd give the story a 9/10.
Graphics: There are very few glitches and bugs in this beautifully designed apocalyptic world. I'd give the graphics 8.5/10
Gameplay: There multiple weapons that war uses each having a special ability or fighting style to them, however the only weapon that has a permanent button is the Chaoseater, War's trusty sword of benevolent destruction. The other weapons are mapped to the Y or triangle button. Each weapon as it's own set of moves, but the moveset generally is small. Darksiders plays like a cross between Devil May Cry, Zelda, and God of War. I'd give the gameplay an 8/10.
Music: The music fits the game just right in each area of exploration within the game. I'd give it a 10/10.
Boss Fights: The boss fights generally aren't too hard, but the legions of hell can be a bit overwhelming at times. Each boss, however, has a special cinematic brutal kill that is more than enough to make up for the simple boss fight. Each boss fight can take between 6-20 minutes to beat. I'd give the boss fights a 9.5/10
Total: 45/50 or 9/10.
