The most original entry to the Eurovision Song Contest was Australia, both musically and visually, and they deserved to win, and the music critics seem to agree with this too.
The actual winner, the Netherlands, put on an entirely unremarkable show.
The audience favourite, Norway, had a fairly interesting concept with the joik singer, but it would've been unremarkable without him. Inserting joik into pop music isn't a new idea - it's just new to Eurovision audiences.
