With regard to the original reason for this thread, I think five women going in a row is also to do with who they picked.
Ashthon was boring, too much attitude, and her voice was not as good as everyone thought. She did have a Diana Ross edge - in that she seemed so old fashioned. Not really her fault, they wanted her to do diana ross.
Naima was rarely in tune. An interesting performer though, I believe if she was a better singer she would still be there. So I can see why she didn't get the votes.
Thia had no spark. Admittedly, a cute guy with no spark might have lasted a bit longer but even so, I can see why she went last week. If she wanted it more, and was prepared to give more to the audience, she would still be there. She seemed popular in polls before the lives. I don't understand how someone can be so determined to be a singer and yet not see the need to put on a show (I don't mean over the top theatrics, I mean a compelling performance).
Pia and was unlucky to go when she did. Yes, she didn't move much, but she isn't used to that sort of thing and wasn't given a chance to improve. Overall it was still a good performance, expectations were just too high,
I also thought Karen would do better than she did, but I found her really dated, especially when she did her Selena tribute. She seemed older than her years.
So I supposed what I'm saying is, there are reasons for them to go, it's not completely ridiculous, but that doesn't really address whether there were more reasons for the boys to go.
