I tried to enjoy this, I honest to god tried.
Being a fan of the US and UK versions of WLIIA, I tried to get into the Australian concept, but there just are any good improvisation comedians on television. They chose a poor selection of television comedians who are not good at improv. Tommy Little is not a natural host either. Too stiff and "me, me, me".
What made the US and UK versions so good was that they used incredible improv actors and didn't worry if they were known or unknowns on television. They knew that if they were good enough people would watch and become household names because of their ability. Here we have the best household names they could find to make the show popular at the expense of the comedy.
It's no surprise this didn't rate and got canned quickly.
