The Flash is probably the most popular show of the Arrowverse and ongoing with an impressive streak of 7 seasons and an 8th one upcoming. When it first aired, people actually liked the first season due to its intriguing plot. While season 2 was not bad, it had some issues like retreading an earlier twist. Season 3 is generally considered to be the decline as writing became nonsensical as we started to get bad villain, with the worst being cicada, same hallway talk, Barry acting like a useless idiot despite being the Flash, the Rogues being lame/underused and season 7 gives us this bizzare family plot line. Just what went wrong with this show?
