I found this to be more interesting as a work of history than as a self-help guide or practical guide on strategy. That said, I think it's unfair to criticize it for "stating the obvious" as I've seen some comment. What's in Art of War is only obvious because it's been influencing works on strategy for thousands of years.

Because it's been influencing strategy for thousands of years, most of the best bits have been retold in other works, and often using more contemporary anecdotes to explain the principles presented. Still, as a general work it's often more succinct and to the point than many more modern works.

Well worth a critical read.
