Agreed. The problem with page-curl in this case is that the left-hand-side of the book is a blank page. This means that when you're "curling" the page, you don't see a a bunch of text/images mid-transformation (mid "curl"). Also, there is no transparency at all to the "paper" - it's totally opaque. If it were semi-transparent, you would see the other side of the page bleeding through, giving some context/reality to the curling.
