Overall, an interesting book.
It's good to know going in that McCarthy does not use quotations in this book. If you go in without knowing that, you might feel some resentment toward him. For the most part, the reader knows what's going on despite the lack of proper grammar. There were a few times I had to go back to figure out who said what, but in general, you can figure it out by what they say. The text jumps around a lot, which adds to the confusion, but for the most part you can figure out what's going on.
Plot-wise, this book was fantastic. The first three-fourths of the book had me reading like crazy to know what happened next. I don't really like crime stuff all that much, but this one was written in such an interesting way that it worked for me.
Then something big happens about three-fourths of the way in and the rest of the book is filled with a lot of symbolism and philosophizing. This in itself wasn't bad, but again, that resentment crept in and I was a little annoyed with the anticlimactic ending.
I have not seen the movie and had little knowledge of the plot going in, so I had no idea what to expect. There is definitely a lot going on in this book so if you want a book to read in order to relax, I would choose a different one. This was involves too much brain power and critical thinking. Again, not bad, but you definitely have to be in the right mood for it.
