Welcome to the world of karaoke, If you are a 14 years old female you will like and believe that what you see is entertaining, for the rest of us its the same old tripe that we have got used to for the last five years. No I don't watch it (it's just hard to avoid all the hype in the media).
In my opinion the voting can be rigged and then the shows screaming host pretends that the "public have .............(long pause)........decided" when the "winner" has already been chosen. But keep on voting as many times as you like (hummm isn't that illegal....vote rigging anyone) the production company really needs your votes err money.
Forgive me if I am wrong but I always assumed that judges have to be independent with no attachments to the contestants. Enough said.
