Sad really.
If either Calum or Issac win BGT then that proves that BGT is just used as a stop gap between two series of X Factor.
I always thought the purpose of BGT was to find an act suitable for Royal Variety.
Paul Potts would never have won X Factor singing opera. He remains one of the best winners BGT produced. Diversity, Spelbound and Attraction also remain three excellent winners of BGT. Ashleigh & Pudsey was also cute and therefore a good winner and George Sampson was good at the time (even though I preferred the act that finished 2nd that year)
It's the other singing "winners" that have failed to wow me. Collabro were good - in retrospect an ok winner but Jai McDowell will always be the most baffling winner.
Looks like 2015 is also going to produce another underwhelming winner. Such a shame when an act like UDI are there.
