Was Brunnhilde really much better? After all she was lying there waiting for her Prince Charming to come and rescue her(typical). Then Siegfried got drunk and decides how funny it would be to start a trio (swinging, is it called?) with Gunther and Gudrun...When she finally finds everything out, she starts breaking the dishes, including the pyre where this Nordic playboy Siegfried (can't really understand what makes him so attractive) was being burnt. The classical description of female hysteria. Is that what you miss in LOTR?
Honestly, Wagner's music is outstanding, but the plot of the (other) Ring is that of a soap opera, and a bad one, too.
