20 Most Hotly Anticipated TV Scenes Of 2017

20. Runnin' Home To You - The Flash/Supergirl

As a big fan of a) superheroes, b) musicals, and c) musical moments in traditionally non-musical TV shows, I cannot wait for the upcoming Flash/Supergirl musical crossover.

The whole episode sounds exciting, with Glee alumni Grant Gustin and Melissa Benoist joined by Broadway vets like Jesse L. Martin, John Barrowman, and Victor Garber. There's also Darren Criss as villain Music Meister, and a song called Superfriends from the brilliant Rachel Bloom (Crazy Ex-Girlfriend).

The most exciting aspect, though, is the song Runnin' Home To You. It'll be performed by Gustin, which is good enough, but even better it's been penned by Benj Pasek and Justin Paul, the songwriting duo behind La La Land's many hits (the lyrics, anyway).

Given how perfectly they were able to write lyrics that encapsulated the themes of the movie and were incredibly catchy, it's super exciting to see what they'll do with The Flash.
