I've tried the demo and is really boring. =(
What'd you expect from a title like "The Graveyard"? It's not meant to be exciting. It gives you the chance to experience a small moment in the old woman's life. Not much happens, but it's more meaningful if you use your imagination and read into the circumstances of the situation.
Another pretentious game that tries way too hard to be artistic and philosophical is the one that I just finished playing yesterday, Metal Gear Solid 4.
Imagine in the graveyard sequence at the end, if Snake had just done something similar to the above old lady scene instead of having a long winded conversation explaining shit that I didn't really care to know. On the other hand, right before that ending when Snake was crawling through the tunnel blasting with microwaves as he gets progressively weaker forcing you to jam on the triangle button with increasing frequency, was quite powerful and engaging. It really allows you to feel Old Snake's struggle to push through with all his will.
That's the problem with Kojima though, he has a message to deliver in his storytelling but he just does so in such a convoluted way. Sometimes I'll be listening to some dialogue in MGS4 that makes me realize how insightful Kojima can be sometimes. And then he goes and makes characters spout some long drawn out inane explanations.
