The Voice, 8 p.m., NBC
The competition moves to its next phase this week with the Battle Rounds. You remember, it's the thing where two members of each coach's team face off in duets, and the coach can pick only one. Well, we hope you remember, because this show was only off the air for two months before this new season started. Can you tell we're getting a little tired of this show? Give us a chance to miss you, The Voice!
Marvel Studios: Assembling a Universe, 8 p.m., ABC
Look, it's Disney/ABC's latest attempt to milk the Marvel franchise for all it's worth! This hourlong special goes behind the scenes of Marvel Studios, and includes sneak peeks at Captain America: The Winter Soldier, Guardians of the Galaxy and The Avengers: Age of Ultron. Ugh. Marvel is like that kid in high school who just wouldn't stop bragging about how involved he was in everything. We get it! You're so accomplished!
Glee, 8 p.m., Fox
Gwyneth Paltrow and Kristin Chenoweth reprise their guest roles for the series' 100th episode, a two-parter that also includes appearances by Amber Riley, Dianna Agron, Mark Salling and other cast members rarely seen these days. Wait. This show has only been on for 100 episodes?! It feels like 1,000.
The Americans, 10 p.m., FX
Just when Philip and Elizabeth think they can relax, an old friend returns to give them their next assignment: intercepting a valuable target and taking on a rogue mission without Mother Russia's support. Ah yes, that classic problem all parents face.
Doll & Em, 10 p.m., HBO
Real-life BFFs Emily Mortimer (The Newsroom) and Dolly Wells (Bridget Jones's Diary) are the stars of this new semi-improvised comedy series from England. Any chance to watch two people casually gab in British accents — we'll take it!
Parenthood, 10 p.m., NBC
Are Joel and Julia back together yet? No? Ugh.
