It was a magazine article so I'm not sure if they bothered to archive it on their website but it was from EGM I believe. Basically the reviewer talked about how he couldn't bring himself to finish the game, no because its bad, which he goes on to explain in detail on why its awesome, but instead he talks about how killing the Colossus seemed wrong to him, instead of a victorious fanfare, you're treated with a slow sad melody and some increasingly disturbing bits. He basically just felt it was morally wrong to finish the game because of what it asked you to do.
