The CW on Thursday went on something of a renewal tear, picking up additional seasons of 10 current series — aka nearly its entire lineup. The list of shows confirmed to return for the 2019-20 TV season includes The Flash, Arrow, Riverdale, Supernatural, Supergirl, Black Lightning and DC’s Legends of Tomorrow. Freshman entries Charmed and Legacies also scored renewals, as did (wait for it) perpetual cellar-dweller Dynasty.
