An enjoyable little book that did a pretty good job of simply and clearly explaining 'The Key Ideas' of Nietzsche - very god for absolute beginners to academic philosophy.
I was glad that Jackson included ample detail of Nietzsche's personal life.
The main weakness of the book is that Jackson fails to maintain the objective, outside perspective upon Nietzsche and his philosophy as he intends the book to have. Jackson includes sections of the different ways to read Nietzsche, different viewpoints and analyses etc. - but in spite of this, his own viewpoint shines too strongly, namely through the tone of his writing. I found myself frequently getting frustrated that he was trying to influence the reader too much to adhere to his own view of Nietzsche rather than providing an objective view and allowing the reader to come to their own conclusions. To a certain extent this is inevitable in any book, but I thought he could've done a better job of it.
However, if you maintain a critical eye, it remains a very good, easy introduction to a complicated philosopher.
