Needless to say, fans of the show were very displeased with the channel's decision and took to social media sites to express their disapproval.Beebos Legends Podcast@BeebosLegendsLots of shows have been saved by the fans in the past.

The Legends are stuck in the past. So they leave clues for the Flash to find them and bring them back to present. All while wrapping up each characters individual stories.8@michaelp93 They could do a back door episode with the flash. The Legends are stuck in the past.
