Batman/Dark knight comparisons are unavoidable, and ultimately hurt the show, however look past these and persevere and you will be rewarded. The set up is very much like Batman, the first few episodes are pretty strong despite this, however it soon meanders with family drama and forced love stories and lacklusture villains. However it starts to pick up again and in the second half of the series it really gathers speed turning from average to not only a genuinely good show but has an excellent series finale, one of the best I've seen on an action/adventure TV series. While none of the cast are going to win any awards for their work here, for the most part they are pretty solid. Stephen Amell is better than most give him credit for, there is such a difference in oliver between the old/early times on island and the man that comes back. He does to stoic hero very well. Diggle is the heart of the show and adds a more relatable everyman touch from the millionaires who are hard to sympathize with. The action scenes are a little quick cut and stylized for my tastes early on but this is improved later in the series. Manu Bennet and John barrowman add some weight to the cast later as well, providing some of the more interesting story elements. Well worth watching.
