As another reviewer elegantly said, Pinter reads like a storybook rather than a formal text. As a first algebra textbook (e.g. a second or third year undergraduate taking group/ring theory for the first time), this is really great, it gives a somewhat romanticized view of the field. Fun to read the first time. However, I'm withholding my 5th star because of its complete lack of "replay value" - if you want to go back and just look at the theorem in plain wording, well you are out of luck, because every chapter is full of lots of background fluff (as a consequence of its storybook style writing).
