God bless the ambition and the heart of this thing - I can see why it has a following -- but it is just not very good.

The tone and the fear/trust mechanic had me hooked early on, but the latter is not fleshed out nearly enough, and feels a bit like window dressing. Then the game descends into a quite terrible action adventure/third person shooter in the second half, with awful boss design and checkpointing, squandering any good will earned earlier on.

Just watch the movie.
