Oliver as a killer was certainly compelling from the beginning, but he was also much too intense for the show to be any fun if every episode was just going to be him living a double life and delivering expository voiceovers. Luckily, Arrow didnt take too long to figure out that the way to make Oliver more likable was to give him some likable characters to interact with openly. Diggle joining Olivers mission was a relief right off the bat just because Oliver having somebody to talk to meant that he could stop with the terrible voiceovers. Oliver also began to feel more human with Digg as a companion. Felicity coming on board brightened up the lair as well as the brooding boys lurking in it. Once the trio of Team Arrow established, Oliver got to show a funny side in addition to all the gloom and doom. He finally felt like a real person, and he became a character worth rooting for instead of just watching.
Fiction buff and writer. If it's on Netflix, it's probably in my queue. I've bought DVDs for the special features and usually claim that the book is better than the movie or show (and can provide examples). I've never met a TV show that I won't marathon. Follow on Twitter @lah9891 .
