Flash coming back?

Is Flash coming back? I miss it. i also loved it. If its not why? im just wondering it was such a hit everyone was watching and talking about it.
Who else think Flash should get his own movie?

The Flash is coming back this season from the speed force prison. It's too bad they used another actor in Justice League as the flash. The tv show flash is the best!

Flash just seems like such a disinteresting character. As someone who has never seen, nor do I plan to watch the series; I don't see the appeal in watching someone run around at the speed of light, effectively invincibly.
