If you are a beginner in Econometrics, this is not your book. The notation is purely mathematical, and the derivations are all very succinct. So, if you are looking for a book to start in econometrics, I would rather suggest Wolldridge's "Introductory Econometrics", which is a wonderful first course in econometrics.
Verbeek's book offers a "guide", giving an overview into the field for people with solid background in Linear Algebra, Real Analysis and Mathematical Statistics. If you feel your knowledge in these fields is rather shaky, I would take Wooldridge's textbook instead.
The four stars instead of five are due to the very complex and sometimes too dry explanations. The book has also a different pedagogical method and format than American textbooks. If you are used to American textbooks, you will find it rather "boring": no colors, hardly any thing other than factual stuff.
