her voice isn't enough to stand by itself. It would have been way better if she had backup [main]/duet. It's not bad; I just don't think it's enough personally.
Debatable. Like Turkey, some claim it's in Europe, some claim it's in Asia. Some even claim it's in both. Also, if you didn't like the results of the show, you're an anti-semite.
I don't think there's any debate on whether Israel is in Europe or not in context of the Eurovision. It's not. That's not the reason it's in the Eurovision. "Israel was able to enter the contest as the Israel Broadcasting Authority (IBA) is a member organisation of the European Broadcasting Union, which is responsible for the event." - Wikipedia
Israel and Australia joined Eurovision because they are members of the European Broadcasting Union don't forget they aired Eurovision in America too on logo tv but you have to admit that Netta was awesome if you don't like her cause she's Israeli your the anti semite
