It wasn't a superheroic Monday night for WBTV's competing DC Comics shows, and the pair sharing a timeslot on competing networks may be working some negative magic for both at this point. Supergirl in its third week continues to garner great reviews for CBS, but dropped a huge half a point, from 2.2 to 1.7 rating. That also meant a total viewers drop from 8.9 million to 8.17 million. The show debuted at a 3.2, and while that was clearly unsustainable, a nearly 50% drop is cause for (mild) concern. If it levels off in this range, though, it should be in good shape.

Gotham, meanwhile, dropped the one-tenth back to a 1.5 with 4.14 million total viewers. It's only a tenth, and shows wavering in that way week to week are extremely common. The show is doing well for Fox, and is held to a different standard being on that network, so fans don't need to worry about the small drop.

Fans of Nathan Fillion on TV also saw a tenth-point drop for Castle, bringing it to a 1.0.

NBC won the night in both the key demographic rating and total viewers categories, with big nights for The Voice and recently early-renewed Blindspot, which hails from DC Comics TV superproducer Greg Berlanti.
