Found it pretty fun to read what is basically a villain's diary. Like all good villains, he thinks he's the hero. He does get what he deserves but I felt that it was underwhelming, like his comeuppance wasn't satisfying enough. I wanted even worse things to happen to him. The ending just didn't cut it for me. Because of the diary format, I was denied the opportunity to read what actually happened. I didn't feel enough schadenfreude .
There were also a few typos I found when reading that took me out of the story.
