CW renews 10 shows, including Riverdale, Jane the Virgin, Crazy Ex-Girlfriend and Dynasty

Variety

Black Lightning, Arrow, The Flash, DC's Legends of Tomorrow, Supernatural and Supergirl will also be back next season. CW shows yet to be renewed include The 100, iZombie, Life Sentence and Valor. The most baffling renewal is Dynasty. "Midway through its freshman run, Dynasty recently slipped to an almost mythical 0.1 demo rating, though Nicollette Sheridan’s debut as Alexis seems to have resuscitated the numbers, some," as Matt Webb Mitovich points out. UPDATE: Rachel Bloom tweets Season 4 will be Crazy Ex-Girlfriend's "final season."
