4 stars for the writing style. It was as so many others have said, completely beautiful, especially given that this was not the author's first language. 3 stars for the story itself (I found myself skimming a lot of the scenes without Lo which didn't interest me. Lo was the magic of the story after all, in all her bratty glory). I am glad that I read this one. It had been on my shelf for quite some time. 
 Often, I think people find something wrong with people when we start to understand why a person would act in a criminal manner. Understanding does not necessarily equate with approval. Nabokov chose a way of laying the groundwork early on, in order for the reader to be clued in on why his character would think and act the way that he had. The loss of love in a pivotal point of life can, in fact, shape your whole world and how you see it for the rest of your life. That's exactly what happened in this case, and it made sense why things came together the way they did. 
 I know someone's going to think me odd for recommending the newer movie version of Lolita but if you want the one that (I think) matches up more with the feel of the book, check out the 1997 version with Dominique Swain and Jeremy Irons.
