Alan Richson was kept on for awhile because he was great looking and had charisma, and the judges kept hoping (in vain) that he would show some singing ability as well. Given the almost nonexistant male singing talent that season, they had little to lose. Richson did set some kind of record for sleeping with more female contestants the season than anybody else (except maybe Simon and Nigel). Scooter girl wasn't great, but IMHO she deserved to make the semis anyway. Not only was she was incredibly hot looking, but she also had a better voice than some of the women who did (Kara Master Bates, Bree the dyke, Heather Pickaninnie, Leah Labelle, Mantasia, etc). I don't know what went wrong with Dina Lopez - maybe she just couldn't take the pressure.
