I suppose some of the negative reviews are fair, but on their whole, I also think of them as unfair and a result of the same problem that has plagued the X-Men trilogy, unfair expectations.
Knights of the Inner Sea shouldn't be a book that is designed to augment your sorcerer. This book will be rather unvaluable to such a person. However, if your desire is to play a Knight from the Inner Sea region of Golarion, this book would make a fantastic addition to your collection!
The leadership feat is generally not a favorite of gaming tables, and the necessity of the mount to the success of the Cavalier class has been much-maligned. However, when thinking of a Knight, we conjure images of two warriors riding toward each other in a joust, commanding their steed to be a part of the warrior in battle. And almost always, a squire is standing in the background, ready to give his liege another lance or assist in donning a suit of armor.
So, to call this book broken or weak is unfair, it is using the image of the Knight that has become a fantasy mainstay as its base.
With that said, I would have liked some more options, but I'm not sure what those would have been, I just know that I wanted more!
All-in-all, this will be an incredibly useful volume for me when I create my own Knight of the Inner Sea, both in building the statistics and in the Role-Playing of the character.
You don't need to lower expectations, just correctly position your expectations.
