Eva McCulloch

Eva McCulloch is the main antagonist of sixth season's second half of the Flash. She serves as the second Mirror Master

Why She Sucks:

 * 1) She's a genderbent version of Evan McCulloch, the second Mirror Master.
 * 2) She has the personality of a sadistic, insufferable womanchild who will never grow up and learn how to work her company, correctly.
 * 3) She's just filler who is the main antagonist of the second half.
 * 4) She initially comes off as a very shaken but kind woman who has been trapped in isolation for six years and becomes literally evil for no reason.
 * 5) She is indeed rubbish and very unlikeable.
 * 6) Despite being unlikeable, she gets a lot of screentime.
 * 7) Her childish motivations don't make any sense, since Eva has been having her mirror clone of Iris collect technology for her, including the Mirror gun, tried to go back to the real world to get revenge on his husband, Joseph Carver, for leaving her in the mirrorverse.
 * 8) Despite viewers expected to "sympathize" with Eva, since she believed that a dimension existed with inverse properties, has been using her powers to exact her plan of "liberation", most likely from the Mirrorverse, she is actually a paranoid yet driven individual who believes solely in evidence and will do anything to achieve her goals.
 * 9) She killed her husband and showed no remorse.
 * 10) Eva is shown to be manipulative and pretentious to her own advantage; such as she lied to the public about the murder of Joseph Carver and framed Sue Dearbon for it, and also manipulate Iris by faking failure and pretending to be broken. She insufferable ruthless into getting what she wants by which she killed Joseph, proving how vengeful she can be, making her a villain sue.
 * 11) She is one of the most hated Arrowverse characters and villains.
