I don`t watch TV a lot, but when Star Academy is on I can`t get enough! Star Academy is a pop music talent contest. Contestants live in a boarding school and attend singing and dancing classes and are filmed with hidden cameras day and night. It`s very entertaining! Once a week, the contestants take part in live music performances. They are all competing ... that`s what makes the show so interesting! Each week either the group members, or the millions of TV viewers, decide which person is eliminated until there is one winner. The eliminations are always so exciting because you don`t know whether your favourite person will stay in or will go. The winner is awarded a record deal or a cash prize and, what is more important, the winner gets the chance to become a successful music artist. I love everything about this show!
