It's clear that Emma's enthusiasm for the show has died over the years since she became host (I think the crowd and the Ashleigh-being-stripped-of-PowerHM-gate has triggered it). It's sad to watch BB14's live shows and compare them to the current days because of how drastically different they are. Hopefully the changes to the set will revive some interest in the show in general.
It's disappointing that Emma is airing her hesitation towards BB in public though, shouldn't this be kept private for a bit.
