Shaun was good, but he is just as good as any other singers out there.. he should have applied for the X Factor.. I agreed with Piers that this show is all about variety and Gareth's act was diverse and entertaining. He should have gone through with Flawless in my opinion.
Simon saying Shaun to go through straight away just goes to show that Simon doesn't care about variety. He just cares about the acts that can make him the most money e.g. singers.. and dressing up Britain's Got Talent as a "variety show" is just another platform for him to do this... or maybe this was already blindingly obvious...
