This is a book which simplifies QFT in a way not suitable for learning the real principles and theoretical foundations of QFT. It uses the synthetic path integral approach only, whilst the canonical approach is more appropiate to understand the foundations of QFT. For this, it is not enough to know how to write down the path integral and calculate scattering amplitudes only. It is good for an experimentalist, who wants to apply the theory of QFT to his measurments and vice versa. Who wants only to have a glance at QFT (including recent developemants) without being too superficial, the book of Michele Maggiore or the book of Thomas Banks are more useful, exactly because they present both approaches. For a major in QFT the book of George Sterman can be recommended.
