Hell's Kitchen Review

I love this show, but since Lacey (last season) I wonder if this show is staged.  She was a terrible "chef" that had no business there, and why she stayed most of the show is beyond me.  This season, a chef from last season just happened to be sitting out in the dining area and he was asked to come back to the show because one of the contestants were not good enough, within 5 minutes of the show.  Another "contestant" that same day was crazy and cracked for no reason...security had to get in.  Are these people proof of the show having fake contestants thrown in for the ratings????  I also hate the fact that every contestant smokes every season, and they all have bad language...those combined definitely give you a dirty mouth
