Not sure about bloomy, but blurry is specific Dishonored's art style - apparently, the textures were designed to feel washed out and blurred into each other.
Yeah, but it's not just that. The whole game just feels so... Unreal Engine.
Despite this, though, the game is quite fun. Like a mix of Deus Ex and Thief. Should be done with the first game soon. Not sure if I'll pick up the DLCs as well or just head straight to the second game.
