The CW is keeping their long-standing promise to continue to build the already impressive Greg Berlanti ‘Arrowverse’ of DC Comics characters with 4 series pick ups! Sure, 3 of the 4 were already established on the network, but it’s still nice to be able to report renewals rather than cancellations.
In this crop-
“The Flash“

“The Flash” will be back for an 8th season! We also have a synopsis for the upcoming season:
Barry Allen (Grant Gustin) lived a normal life as a perpetually tardy C.S.I. in the Central City Police Department. Barry’s life changed forever when the S.T.A.R. Labs Particle Accelerator exploded, creating a dark-matter lightning storm that struck Barry, bestowing him with superspeed and making him the fastest man alive — The Flash. After a thrilling cliffhanger last season which saw the new Mirror Master (Efrat Dor) victorious and still-at-large in Central City, The Flash must regroup in order to stop her and find a way to make contact with his missing wife, Iris West-Allen (Candice Patton).
With help from the rest of Team Flash, which includes superheroes Caitlin Snow (Danielle Panabaker), Cisco Ramon (Carlos Valdes), Ralph Dibny (Hartley Sawyer), and Nash Wells (Tom Cavanagh), as well as the Flash’s adoptive father Joe West (Jesse L. Martin), Meta-Attorney Cecile Horton (Danielle Nicolet), tough cub reporter Allegra Garcia (Kayla Compton) and brilliant tech-nerd Chester P. Runk (Brandon McKnight)… Flash will ultimately defeat Mirror Master. But in doing so, he’ll also unleash an even more powerful and devastating threat on Central City: one that threatens to tear his team—and his marriage—apart.
