2.5 stars. I stopped reading all the words at about 60% in,and then skimmed until the end. 
 The idea of the book, living a life over and over again (maybe until you get it right?) draws me in fully. Plus, Atkinson writes well, and knows how to develop a character. It's the execution of the idea that failed me. 
 I felt it was plodding, dull, more repetitive than necessary, and didn't leave me with any feeling of completion. Rather, more questions went unanswered, which is a feat in such a large book. 
 I wanted to love it. After the novelty of seeing how Ursula would die and be reborn wore off, I wanted it to get better. In the end, I decided that this would make a much better movie than it did a book, and that's a rarity. After all, I love Groundhog Day.
