These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Awesome Music: "Jesus, Take the Wheel" and "Just a Dream" are considered among her best. "Blown Away" likewise.
Cliché Storm: "See You Again" is four minutes of "you're dead, but I'm not sad" clichés that have been done a million times. It also sounds like all the "sad" songs you always hear on movie soundtracks (it was written for one of the Chronicles of Narnia films).
"Some Hearts" was first recorded by Marshall Crenshaw back in 1989.
She subverted this with a cover of Randy Travis's "I Told You So". A radio station started playing a version that spliced Travis' vocals into the original, so she ended up releasing a remix that had a newly-recorded vocal track from Travis (while also removing Vince Gill's backing vocal). Also led to a Funny Moment when she first performed it at the Grand Ole Opry, where after she did it Randy Travis came out on the stage behind her. The audience stood up and starting cheering, and Carrie looked behind her and squeaked "Oh my gosh!" Randy then told the audience that Carrie's voice was a lot better suited to the song than his.
Ear Worm: "He's a good time cowboy casanova, leaning up against the record machine..."
"Good Girl" is quick to rival that.
Harsher in Hindsight: "Blown Away" became this after an F5 tornado destroyed the town of Moore, Oklahoma (in Carrie's home state, no less than is mentioned in the song).
Moment Of Awesome: Her performance of "Alone" on American Idol provided her page quote and is still cited as one of the greatest performances in the history of the show.
Never Live It Down: Her performance in The Sound of Music Live already seems to have become one, with the poor woman crucified across Twitter during all three hours. Her less than tactful response to it, saying that anyone who didn't like it "doesn't have God in their lives," didn't help.
Adding to this is the fact that living members of the real life Von Trapp family felt that she wasn't the best choice for the part of Maria. At least one member of the family, the great grandson of the real life Maria, said that while he thinks Underwood is a great singer, she just isn't a good enough actor.
