This is so not one of her favorite things!

Kym Karath—who starred as Gretl in the 1965 film adaptation of The Sound of Music—has spoken… and her reviews for Carrie Underwood’s live stage production of the classic play are pretty harsh!

On Twitter, the actress said that she was “mystified and disappointed” by the special, and that she was only happy with Stephen Moyer, who played Captain Georg Von Trapp.

But the 55-year-old woman who played the youngest Von Trapp’s backlash didn’t stop there!

She went on to say that some moments were “painful to watch,” and slammed the casting choice of Carrie Underwood.

Fans React to the Casting of Carrie Underwood in ‘The Sound of Music Live!’

“Love Carrie Underwood, but this role is just not right for her,” she wrote on Twitter. “She is lovely her voice is beautiful but acting is wrong.”

In addition to the True Blood star, Kym praised the performances of Laura Benanti (Baroness Elsa Schraeder), Christian Borle (Max Detweiler) and CJ Wilson (Herr Zeller).

The best part of all? Kym got together to watch her on-screen, Von Trapp siblings! She tweeted that she’d be watching with Charmain Carr (Leisl) and Angela Cartwright (Brigitta).

Aww! We really hope they all sang along together!
