JEEZE.
While the secret ending was hilarious, I felt the game was WAY too difficult to justify such a "Meh" ending. I can only guess what the normal ending entailed from what I've heard and observed, and it seems to me that it was even more unsatisfying.
Despite these (less-than-minor) quibbles, the game was still enjoyable, and extremely well thought out. The atmosphere was just great, invoking an unshakably foreboding air of palpable dread. While the endings may have spoiled it for most, I found the overall experience to be rather worth bearing.
