usually the x factor just does a bottom 2 and lets the judges decide who goes home but i like american idol's format of doing a bottom 3 each week, as it would help people like ella and james this year, laura from series 5, luice from series 6 etc... last longer on the show because there fans would know there in danger, only doing a bottom 2 every week doesnt show us who is close to the bottom as much as a bottom 3 would, it might save a few people and would make the show more interesting in my opinion.. it might also give us an idea of who really is leading the votes each week. i also think they should revile who the bottom 3 is near the start of the results shows, send one to safety and let us vote between the bottom 2 throughout the night and revile the results at the end, the sing offs mean nothing anyway
and the reason behind this?
