Yeah, I like deadlock.
I remember when there were 4 judges for the first time on XF I didn't like it, but once it went to deadlock, I started to like it, especially as it's the public vote that decides who gets the lowest.
Plus going back to the audience, I think they're annoying and take away from the act in the audition. Compare Seasons 1-5 of XF to seasons 6-7. It's more entertaining watching the judges faces as the singer ruins a classic song, without a rude audience going "BOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO".
