Can't Get No Satisfaction

The first time I re-read the entire Harry Potter series, I felt pretty unsatisfied with the outcome and this time around was not any different. I have several reasons for this lack of satisfaction. One of them being that I still think Luna and Harry would have been a hilariously wonderful couple, but my frustration made be based on the terrible portrayal of Ginny Weasley in the movies, but I digress. I am well aware that J.K. Rowling could not have answered every question presented in the series or go into a great amount of detail about several different characters, but after seven books there are so many questions left unanswered.

I would have loved to know what happened to all the wizards who were Death Eaters. What happens in the 19 years between Voldemort being defeated and the epilogue? That is the biggest question I have. Once Harry puts the Elder Wand back with Dumbledore, how does he really make sure no one can get to it again? Is there a possibility that one of the Death Eaters chooses to become the next Voldemort or were they all just doing it because they were scared? Do Draco Malfoy and Harry Potter have dinner parties and talk about the times they basically tried to kill each other? I know J.K. Rowling must want the reader to use their imagination, but I just have so many questions that cannot be answered. As much as I love this series, it is hard to have complete satisfaction with everything.
