Damn, yes. It totally ruins the immersion and it makes the game world seem distant and uncanny. Have you seen those textures? Very ugly, and this is 2012, ey! This game needs to be built on the CryEngine!!1

Of course not. The game is fine the way it is. The darkness serves a clear purpose. If you could just see everything. The rest are simply coding or engine issues. Who the hell cares if it doesn't look THAT good, it's simply good enough to be scared shitless.
And about the purpose of the game. It only has one purpose; that's being scared. Of course it ends that way, it's exactly what it wants to do. It's about the buildup and being caught. Getting all 8 pages and then being caught is the ultimate achievement in the game. It's how you get there (and how often you don't make it) that determine the experience.
