Rules of Engagement (CBS, 8:30 p.m.) — Series finale. One hundred episodes. That’s how long Grown Ups prequel Rules of Engagement has been on the air. One hundred goddamn episodes. Happy Endings? Fifty-seven.
Adventure Time (Cartoon Network, 7:30 p.m.) — “Peppermint Butler believes Bubblegum could use a suitor to get her out of her lab.” Just reading that sentence makes me smile. Adventure Time is delightful.
The Goodwin Games (Fox, 8:30 p.m.) — Series premiere. Hello Goodwin Games. This comedy from the How I Met Your Mother guys, about three mismatched siblings (played by Scott Foley, Becki Newton, and T.J. Miller) who return home after their father dies, was supposed to premiere during the 2012-2013 season. Goodbye Goodwin Games.
Defiance (Syfy, 9 p.m.) — “Nolan gets a blast from the past while a Castithan fugitive wreaks havoc in Defiance.” That synopsis should read, “Nolan gets a copy of Blast from the Past on DVD.” Fixed.
Rectify (Sundance, 10 p.m.) — Season finale. Don’t leave us, Abigail Spencer, I mean, Rectify. We need you.
