I like basically "heroes" who are struggling with their past and their own demons (Batman is also one of my favorites) and grow it, sometimes with more, sometimes with less difficulty.
Here it is the creators managed to compile a coherent group of main characters that ensure that for a television series nice a lot of action is shown, but also moral question or even one or the other magic smile on my face. Moreover, I think that the creators have been chosen with a happy knack from the extensive comic universe treasure and a line have remained faithful. Thanks to this, Arrow forfeit not ridiculous, because it is clear to see that those responsible are with heart and soul.
So, I can ultimately only conclude that whoever gets involved in a comic adaptation and can tolerate the occasional hole in the logic / Story, can enjoy a well-told story in two and a half seasons to date.
