Its for 3 people - they go by the names of Sharon Osbourne, Louis Walsh and Simon Cowell! They know and we know that teh act at the end probably won't last because a. tehy just won't have the credibility after winning a TV talent contest and b. they're just not unique anymore - they're made to sing certain songs on X Factor and people just won't think they're original after they've sung boring, predictable and safe songs EVERY single week for the past 3 months.
Simon Cowell is so far up his own a*se its quite surreal that people like him. I think Louis and Sharon see more sense, Sharon because she takes time out to spend with her acts and get to know them - and also she proved that the voting public only like 'safe/ boring' songs - when Maria sang Brown Sugar fabulously in my opinion, she got voted out teh same night - the acts just can't get their own style accross on TV anymore, sadly. Louis because he cares about his acts and he knows what sells, he seems a genuinely nice guy, he doesn't get the credit he should. Simon is the least credible judge on the panel.
So... there is no point to X factor, its not original, its an enjoyable program to watch. I watch for teh judges because they're (at times) funny. Thats all!
