| Crappy Batman for a market over saturated with Batman
Batman is everywhere and so far the only truly successful characterization of a DC character in the entire DC movie/TV universe. Trying to avoid another Batman in market already over-saturated in Batman, but not wanting try anything new, we get Arrow - an awesome character that wasn't awesome enough for WB/CW and so they rewrote his background and gave him all of Batman's villains. Hence this low score review for being unoriginal. The characters are all terrible crappy versions of their comic selves.
TLDR - This show is Batman in Robin Hood Men in Tights.
