Regarding article itself: great.
The patterns that are treated are explained in depth, which allows to understand them, and know when to reuse.
Although being intermediate level of English, the book remains understandable. However, having read the first two chapters of the French version, I prefer humor contained in the French version (maybe because I only have a basic level of English;)).
In short, I highly recommend this book for those who want to learn design patterns having fun.
