I've heard a lot about this book but never came around reading it, now I'm finally considering reading it.

What are your thoughts on this book, is it any good?

Do you have any other book recommendations about business? Since I've some time on my hands right now.

Rich Dad Poor Dad got some heavy criticism tho, which makes me wonder a little bit:

John T. Reed, an outspoken critic of Robert Kiyosaki, says, "Rich Dad, Poor Dad contains much wrong advice, much bad advice, some dangerous advice, and virtually no good advice." He also states, "Rich Dad, Poor Dad is one of the dumbest financial advice books I have ever read. It contains many factual errors and numerous extremely unlikely accounts of events that supposedly occurred."[2]

Kiyosaki has provided a rebuttal to some of Reed's statements.[3] Slate reviewer Rob Walker called the book full of nonsense, and said that Kiyosaki's claims were often vague, the narrative "fablelike", and that much of the book was "self help boilerplate", noting the predictable common features of such books were present in Rich Dad, Poor Dad. He also criticizes Kiyosaki's conclusions about Americans, American culture, and Kiyosaki's methods. [4]

In the February 2003 issue of SmartMoney magazine, Kiyosaki backed off his claim that his "rich dad" was a real person, instead saying, "Is Harry Potter real? Why don’t you let Rich Dad be a myth, like Harry Potter?"
In 2007, Lechter sued Kiyosaki, alleging numerous instances of financial misconduct. The suit was settled for an undisclosed sum over a year later.[5]
