After starting with The Flash, I've started and finished all 3 seasons of Arrow.
Most memorable season 1 episode is where Oliver lectures a vigilante about murdering people and then murders him.
Slade Wilson casting was perfect. Crixus from Spartacus.
Barrowman.
Smallville really put me off the idea of a long running Superhero show, but I've really enjoyed the seasonal story arcs.
Roll on season 4 Arrow, season 2 The Flash and season 1 of Supergirl and also Legends of Tomorrow.
Thea Queen could play Annie from Community's sister.
