The TV show version of Dexter does a great job capturing the feel of the book, especially Dexter’s personality. As in the book, he comes across as both both creepily likeable and morally ambiguous. From watching the first two episodes and googling a bit, it seems as though the first season of this show is a reasonably faithful adaptation of the first book, Darkly Dreaming Dexter. There were plenty of direct quotes and so far I didn’t notice any major plot changes. However, Dexter’s relationship is played up a bit, becoming more complicated and more romantic. Another change is that the pace of his vigilante murders is increased to keep each episode interesting. The whole season is the plot of just one short book after all! Even though the show becomes completely separate from the plot of the books after the first season, I would guess that most fans of the books will like the show and vice versa.
