I am used to see Operas, but I really didn't liked this one. *The audio is terrible, to start.
* Isolde, of the real story is blonde. The lead singer is the opposite.
*They didn't played some of the coolest parts of the story of Tristan and Isolde, and since this opera is so long, time wasn't exactly a problem.
*Too boring.
* Where are the changes of scenario? Usually the best Operas has a frequent change of scenarios. This is vital for us, as viewers, to imagine what is happening in each part of the story. A person that is not used to see Operas, or never read the Tristan and Isolde's story, will be a little bit lost.
