Negative Positive
Title: Great book for upper-level undergrads and first-year grads.
Review: Covers a huge breadth of topics in seismology, is written simply, has great diagrams from important papers ad books, and it's easy to find what you're looking for. I still use it for a reference occasionally, and I'm a 2nd year PhD student. No, it doesn't have the mathematical rigor of Aki and Richards, but when you're just starting out, or if you're more of an observational seismologist than a theoretical seismologist (like me) that can be a relief.
Is the review positive or negative?
