Glee manages to pack an insane number of songs into each episode, which means that there will always be a few standouts along with the inevitable dud or two. We've narrowed the performances down to the very best and the not so great from Episode 2.10, “A Very Glee Christmas.” After all, not every Glee cover can wind up as a bestseller on iTunes!

Best Performance of the Night: “Last Christmas” by Rachel and Finn

Blaine and Kurt were great in their blissful rendition of “Baby, It’s Cold Outside” — but it was lacking the emotional impact that we got in spades from “Last Christmas.” This performance masterfully captured the anguish of Finn and Rachel’s situation, emphasized by the dynamite staging, with the two of them walking on either side of a row of trees. And how about those harmonies (which is another thing that “Baby” was missing)?! We know what you’re thinking: A Wham! song is the song of the week? We’re surprised, too.

Worst Performance of the Night: “Merry Christmas, Darling” by Rachel

There are thousands of Christmas songs out there, and Glee decides to include something by The Carpenters that no one’s ever heard? We think that this bland adult contempo number should have stayed on the PA system of a dentist’s waiting room, where it belongs.

Sure, Rachel showcased her pipes a bit in the number, but the performance certainly wasn’t helped by the dull staging, with Rachel confined to a stool (in her silly beret). The lyrics let Rachel continue to wallow in her pity party. If we had a coupon for one Rachel Berry song, we certainly wouldn’t cash it in for this performance!
