Some say her rendition was flat.

Carrie Underwood was on the biggest stage in the world when she sang the National Anthem before Sunday's Super Bowl, and now everyone is talking about her performance. Watch the video after the jump to see for yourself.

At a press conference last week, Underwood joked that the one thing she was scared of was forgetting the words to the National Anthem. thankfully, it seemed like the winner of American Idol's season four remembered all the lyrics, but many still think her performance was far from perfect otherwise.

Naysayers are calling the singer's rendition of the Star Spangled Banner "pitchy" because of a couple flat notes she hit, but we'd like to see them perform in front of millions of people and try to sound half as good as she did.

So what do you think? Could her vocal chords have used a boost, or did she nail the song perfectly?
