Glee manages to pack an insane number of songs into each episode, which means there will always be a few standouts, along with the inevitable dud or two. We've narrowed the performances from Season 4, Episode 15: “Girls (and Boys) on Film,” down to the very best and the coulda-done-without. Do you agree with our picks?

Best Performance of the Night: “Come What May” by Blaine and Kurt

Was Glee trying to torture us with those flashbacks to how perfect Kurt and Blaine once were? If so, mission accomplished. Regardless, we loved every second of this performance, from the killer vocals to the adorable slow dance. We also love how the producers seem to have said to themselves, “We bought this fog machine, so dammit, we’re going to get our money’s worth.”

Worst Performance of the Night: “You’re All the World to Me” by Schue and Emma

Another fantasy song performance but a less successful one was Wemma’s black-and-white duet. We weren’t crazy about “Diamonds Are a Girl’s Best Friend”/“Material Girl” either, but the sleepy, misguided “All the World” was more forgettable vocally. Still, the gravity-defying effects were cool and Schue can wear a vest like nobody’s business.
