Arrowverse: Every Season Ranked Worst To Best

The Flash's debut season proved that it could follow in Arrow's footsteps, but it wasn't long before it started to outshine it.

Barry Allen's arrival enhanced things, imbuing viewers with a sense of hope that The Flash would use as a foundation moving forward. And the lighter tone, sense of family and super-powered showdowns were callbacks to the superhero TV golden age.

There's a reason many still consider The Flash's debut season to be the Arrowverse's greatest. Yes, there was an inherent newness about it that made each episode a genuine delight, but the 'Man In The Yellow' arc is the best piece of storytelling the shared universe ever accomplished, providing the light-hearted fun with a gripping core narrative and an incredible villain.
