what is superstar?

what is superstar? recently singapore tv station held a programme called "superstar"...1/9 is grand final....1 male and 1 female to fight for the superstar champiaon, but male 1 is blind...did he can be a real superstar? cos this is a real world, if u are handicap ofcos u can success if u are in other field, but in entertainment field is hard to be "superstar"...thier vote is 30% from judgers, 70% from audiences....i think is not fair....cos got few telented participants already been voted out...so do u guys think that blind people can be superstar?? hmmm....
