I got
Beyond Countless Doorways yesterday and was disappointed.

The book is excellent quality when it comes to layout, art, and the quality of the paper it is printed on, as well as binding. However, I found much of the content simply boring. Many of the ideas are mundane, if not lame. I think I am going to write a review on this book from which I expected so much... But basically, my point is: if you do write a planar handbook,
please, make it something mythological that keeps a sense of wonder and mystery. Cause, it's not what I found in BCD unfortunately...
