Title: must have!
Review: This is an excellent text for QFT; however I'm not convinced it is the best introduction to the subject. At times it can be overly dense and cumbersome with notion. Nonetheless, this is one of the best references out there. In particular, the treatment of bound states in QFT is the best I've seen. Weinberg also provides extraordinary insight into the subject.
