As Primetimer's Joe Reid wrote yesterday, it's become more and more difficult to tell which Grinch is which when consulting the TV listings any given day during the holiday season. Adding to the confusion tonight is Dr. Seuss' the Grinch Musical!, a brand new staged production starring Matthew Morrison in the title role.
Also tonight: The Masked Singer presents a new holiday special, The Great Holiday Light Fight returns for Season 8, and MTV rolls out a new spy-themed edition of The Challenge. Here's what's new and noteworthy on TV this Wednesday:
