To get an idea of how great magnetic and radiant shearer is here, consider that she matches her scenes with Clark Gable, lionel Barrymore and Leslie Howard and wipes the floor with all of them.
Don't get me wrong they are all very good here but this movie is a star vehicle for shearer and it is her movie. She does all of the shining.
If you appreciate her, this movie is a must see even though the film drags on and the script is average at best.
I wouldn't be surprised if this served as an inspiration to courtroom dramas like Perry Mason and Matlock later on.
