Question regarding Umberto Eco

[Juan Cires Martinez]

I would like to ask why is "Foucult's Pendulum" so well regarded in
critical books.  In bookstores I have often browsed through postmodern
literature critical books looking for essays on TRP (never bought any,
that's why I am asking this question) and I was surprised to see how
many of them devoted a lot of pages to that book, which when I read it I
thought it was sort of OK, but after reading GR and, specially, "The
Illuminatus! Trilogy", I thought Eco had ripped off a lot and created
very little.

I just thought that asking you was easier that reading a few of those
books.

Saludos, Juan.
