House of Leaves

Is...Is this book any good, I hear praise for the book a lot, but others seem to say its just piled on with so much nonsense as possible in the hope of confusing people to the point where they shrug and mutter, "I guess that's genius."

So yeah, In short, how does this book fair?

>I started and finished the entire thing in a single day.
I have a hard time believing that.
