Good, but not easy

Like the first game, and worse, this book is not restful. It was like being in the head of the author, and seeing the clash of all these ideas. But the novels and short stories that I like most about Dick, it is often simpler to base, but who give way to the genius of the writer. And since the first game, I still have that feeling of seeing "Ubik" hanging, which is normal since different realities is a theme, if not the favorite theme of Dick and that of course is addressed here. But it bothers me because at that time I like reading a sub Ubik.

In short, a book I loved in certain points, because the ideas are well treated and sometimes brilliantly, but I was a little martyred.
