CBS’ Big Brother opened Season 18 on Wednesday with 6.1 million total viewers and a 1.9 demo rating, easily leading the night in both measures yet down 13 and 9 percent from last year’s opener to quite possibly (?) mark a premiere low.

Leading out of that, American Gothic debuted to 3.5 mil and a 0.7 (and an average reader grade of “B-“), matching fellow CBS freshman BrainDead‘s premiere rating but down from what a Criminal Minds rerun (5.3 mil/0.9) did last year airing after Big Brother’s bow.

Over on Fox, MasterChef (3.7 mil/1.0) slipped 12 and 20 percent, while Wayward Pines (2.4 mil/0.7) was steady.

NBC’s The Night Shift (4.3 mil/0.9) ticked down a bit.
