My 15-year old son granted it 4 stars. I'm closer to 5, so I rounded up for us. This title was a joy to read aloud, since I tried to approximate the joys from the movie's actors. Now we have an excuse (did we need one??) to watch the movie again, and look for differences. 
 The Princess Bride boasts a grand, epic adventure that's seeded in true love. *swoon* There's swashbuckling galore, deception, sneakiness, hunting, love, and plenty of humor. Once in a while Goldman interjects with his opinion about "S. Morgenstern's" writing and choices, which is fine. 
 The only parts I didn't care for were the lengthy intro to the 25th Anniversary edition (or something like that), and the lengthy stuff at the end. My Kindle read 80% done when the book was actually finished; the rest was Buttercup's Baby (didn't read) and that other stuff. But since I could easily skip that, I don't count it against the actual book. Great fun!
