From the Back Cover
An Introduction to Quantum Field Theory is a textbook intended for the graduate physics course covering relativistic quantum mechanics, quantum electrodynamics, and Feynman diagrams. The authors make these subjects accessible through carefully worked examples illustrating the technical aspects of the subject, and intuitive explanations of what is going on behind the mathematics. After presenting the basics of quantum electrodynamics, the authors discuss the theory of renormalization and its relation to statistical mechanics, and introduce the renormalization group. This discussion sets the stage for a discussion of the physical principles that underlie the fundamental interactions of elementary particle physics and their description by gauge field theories.

One discussion that I found particularly helpful in P&S is the explanation for the sign of time dependence for the field operator psi(x) on p.54 using equations (3.91) and (3.92). Because psi(x) is an operator and not a simple wave function, we have to switch to the Heisenberg picture in order for it to have time dependence. In the Heisenberg picture the annihilation operator has time dependence a(p)exp(-iE(p)t). It is then clear that the annihilation side of psi(x) must be proportional to a(p)exp(-p.x), since p.x=(Et-P.r) using Ryder's choice of metric and space time coordinates (with P as the three momentum, r as the three position [x,y,z], and E as the energy). Perhaps this seems like a minor point, but the choice of sign for the exponential in a(p)exp(-p.x) seemed to me to be purely arbitrary before reading this section in P&S.
As you might expect, however, some points that should either be given greater emphasis--or explained in more detail are sometimes glossed over. Happily, a good supplement for this text exists in the lecture notes of Cambridge University's David Tong. Tong's notes provide a better understanding of the ideas behind the rotation of the contour slightly away from the real axis (p.95) in order to insure that the integral for the propagator converges. Tong also adds to the authors' discussion of normal ordering and Wick's Theorem.
Peskin and Schroeder also provide a very readable discussion of the Higg's model in Chapter 20. Reading this chapter has given me the best appreciation for QFT that I have gleaned thus far.
In conclusion, you'll probably wannt Peskin and Schroeder as a sort of 'hammer, saw and screwdriver' text (a carpenter's basic tools are hammers, saws and screwdrivers) but you'll need to go grab other tools every now and then.
