Despite taking on the high-rating World Series on Fox, NBC's supernatural drama "Constantine" premiered to solid numbers last night despite its challenging 10pm time slot. “Constantine” averaged a 1.4 rating and 4.3 million viewers in Live+Same Day numbers, retaining more than 90% of its demo lead-in from the fourth-season premiere of “Grimm” which scored a 1.5 rating and 5.3 million viewers overall. The hope is those numbers will stay fairly firm.
