I don't think of this as a family show at all - too much sex talk for that.....and I don't mean sexuality talk.
The problem I have with the show is that there is just too of the whole "Very Special Episode" lately: stunt casting, theme episodes and not enough focus on what hooked many of us with first episode. Rachel and Mercedes singing 'Take Me Or Leave Me" in the last episode is the kind of thing that made me love the show, not guest appearances from Katie Couric or Gwyneth Paltrow (even though I thought she was good). If they would put the focus on the kids and their talent, the show wouldn't be so uneven.
For my money, the ONLY good theme episode of the entire series was "The Power of Madonna." Every other theme episode has fallen short.
