I was very reluctant to watch this show. It seemed to much like "American Idol", with bad singing, and nasty judges. This show is totally different; the contestants have actual talent, and the judges make critical (but not overly ego destroying) comments that help the performers improve their singing.
Each week, a singer chooses a song and then performs in front of a live audience. Once the show is over, the public can vote via text messaging, or Internet voting. Polls are open for four hours, and then next day the bottom three need to perform an INXS song. INXS then decides which of the performers does not suit the band. That person then gets to say goodbye to their fellow contestants, INXS, and Dave Navarro.
There is absolutely no petty bickering, and if there are arguments, they're resolved with maturity. Even though this is a contest, each performer cares and helps each other - this is what makes Rockstar: INXS different.
