Is this a good book? I'm not an avid reader but I decided to finally properly get into reading, and I started with this, but I've heard some negative criticisms on this book.

I just finished the 2nd part of Atlas Shrugged the other day, and, frankly, I'm quite exhausted with it. Is it worth going through the final act? I'm aware there's a grandiose 50-page philosophical manifesto interjected in there at some point, and I'm quite partial to Rand's philosophy on the whole, but I feel as if I've been worn down too much to merit any further investment into the book. Any advice? Thank you.

>Objectivism holds that there is no greater moral goal than achieving one's happiness.
Why would anyone oppose this? And why does this simple belief make people so angry?
