Two episodes in, I'm still iffy about the show. I'll continue to watch because I do see potential there, but I want them to make better use of the villains. They've pretty much just ran through two Drakon and China White (especially White) that could be season-long villains. Granted there's nothing that stops them from coming back to the show but I don't think their introductions were so good to make the average fan see a need for them to come back. They were treated like run of the mill villains.
Hopefully the show gets better in building anticipation for Arrow's villains from the comics and of course delivering on their promises.
I like the supporting cast. I'm not into the lead actor that much. He's ripped, but his acting doesn't do much for me. I'm hoping that gets better over time too.
