I thought everything outside of the courtroom in this one was good. For one thing there is no way a trial like that would be over so quick. Don't most of those kinds of trials usually take weeks? Also I doubt very much Laurel would be allowed to play that big of a role in the trial given her relationship with the Queen family.
How dare a show about a vigilante who shoots people with arrows and hardly ever get hit by a bullet despite being shot at dozens of times, and feature supernatural events, not be realistic when it comes to courtroom scenes?!
