I think they should lower the Overs age to under 21. That way more talent will go through to the main show as the boys and girl category seem quite competitive. The Over 25 category is quite weak in comparison.
but doubt it will happen this year, but the talent is so tough in those categories they really should think about splitting them.
Was it a bit odd that they decided to make up another girl group from the two that had already failed at their first chance, instead of choosing a girl group from the girls that just missed out on Judges Houses, who presumably they'd thought were better singers?
