Ella was in the bottom 2 because of several factors, none of them being the X factor ...
She's a girl. All other females were removed from the competition in previous weeks. Yes, I know girls can win the X Factor and do well, but it does seem harder for them versus boys and men.
She was probably too sophisticated for a tweenie audience and for an older audience had we not been told she was 16 I'd have thought she was 23. So I think she fell between 2 voter bases.
Wrong song choices and arrangements. She was singing unknown songs (to the ITV viewer) or edgy or depressing, downbeat versions of popular songs. Song choice is absolutely critical. When people say 'she could sing the phone book' they don't actually want to hear her sing the phone book, they want #1 hit songs sung in the version they recognise or a version that lifts them up, not drags them down.
She was badly styled. She's 16 and was dressed like a 45 year old half the time.
She went off the boil for 3 weeks in a row with dull songs. I thought she sang brilliantly this week but the song was a dirge and I agreed with Nicole, I was waiting for it to kick in with a sudden rev up into being a huge, fun dance number. Instead it dragged. Anyway, her momentum was heading down for a month when, for example, Jahmene's and Rylan's were heading up.
The judges overpraised her and I guess a lot of people felt they didn't need to vote for her with all that praise. It seems criticism inspires people to pick up the phone, not praise - look at Chris and Rylan.
