While some claimed that Underwood's Maria was "unbelievable" others said they thought it was "pretty bad."
Underwood herself was rather pleased with the performance writing on Twitter that she "couldn't be more proud."
"Glory to God tonight...I couldn't be more proud. What a tough thing to pull off and we did it! I am so blessed!!!" she tweeted after the show.
Here are some of the reviews her performance got on social media:
Ok, so some of the acting is pretty bad, but you can't have everything. #TheSoundOfMusic— Rob Lowe (@RobLowe) December 6, 2013
Wow! The Sound Of Music Live was awesome. @carrieunderwood unbelievable! I can't imagine the work that went into that. Such a talented cast!— Miranda Lambert (@mirandalambert) December 6, 2013
Bastardizing a true classic w new songs - disappointed. #SoundofMusic— Taylor Armstrong (@TaylorArmstrong) December 6, 2013
The Sound of Music Live is tonight and Carrie Underwood’s “favorite things” should be people who haven’t seen Julie Andrews in the original.— Joan Rivers (@Joan_Rivers) December 5, 2013
@Sayitwithstyle I love Carrie but just don't wanna watch. Julie Andrews can't be touched.— Candace Cameron Bure (@candacecbure) December 6, 2013
