Yes - I take your point about the USA sickly sweet mutual fan club at the end. But Lauren Michelle was by far the most technically gifted, coupled with excellent musical interpretation. Her ability to sing pianissimo at any place in her range was quite exceptional, and a feat that remains quite beyond me. I was blown away by it.
I too thought the South Korean tenor was in the running and may reappear as the wild card finalist.
The tenor from Malta was pretty dire I thought.
I am not mad about the new system whereby anyone who wins a round is automatically in the final. If they are in a relatively "low quality" round (although they are all pretty brilliant!) then the winner might be not nearly as good as an excellent singer who does not win in a round with all better singers.
The singers who get my vote are those where I am rooted to the spot and cannot even post on GNet as my whole being is absorbed in the magic that they weave!
