I thought it was just on here but they're snatching all the polls I've seen (with only Louisa seemingly giving them a run for the prize)
I honestly find them to be very weak, their vocals only sounded smooth at judges houses because it was auto tuned and this week they were so pitchy and just really basic, their dancing isn't even that great. I just see them as very blah and I really don't get why they seem to be dominating so much.
Hopefully it's the Laura White effect and it fizzles out and they flop out in a few weeks
