As much as I look forward to seeing Michael dance again, this move was just plain wrong. The judges made their decision for what they considered to be good reasons - two acts that were excellent but too similar, so they chose the one they thought was better. Simon Cowell should not have undermined those people who were appointed - presumably by him, or with his approval - to do this job. It's unfair, unethical, unprofessional, and it leaves a bad taste in my mouth.
