An essential book at the time, but now more or less common knowledge. The approach is less interactive than expected, and the book becomes quite useless after the introductory chapters.

This is an essential book for any developer, but I tend to believe that the techniques for refactoring presented here can be presented in a more intuitive manner. An accent on code smells would've been preferable. Most of the solutions are obvious and the cross referencing becomes tiresome after a while.
