I bought 'Simulacra and Simulation' second hand after hearing that 'The Matrix' was allegedly based on it (and also cameos in the film for a split second). The book itself is condensed into commentaries on particular topics coupled with critiques from the author and aligning things with a post-modernist viewpoint i.e. the concept of hyperreality in today's world, the use of language.
I thought that in small bite-size readings it does pay off, to an extent though. Like with many of the reviews, especially Markgoats' review, I agree that it is indeed annoyingly difficult where you may feel whether it was worth opening it in the first place or whether you are attempting to get up on your post-modern high horse. It tests the reader in ways that it is difficult to determine what Baudrillard wants us to think (or not think given the paradoxical nature of post-modernism). That said, the obscuring of points and drawn out sentences become second nature and you question whether or not you understand the book at all. Indeed a thesaurus and patience are required to tackle this, and adverse reactions of confusion may follow, but once deciphered like I said it pays off but in select areas. For instance the first chapter is enjoyable and pretty much details what a simulacra is, and it is interesting to delve into the essence of simulated realities without having to believe in them. On the other hand, the last chapter 'On Nihilism' to me dragged and I didn't feel as if I was learning anything about Baudrillard's philosophy.
Thought-provoking sometimes, but difficult and tedious at others
