I didn't see the first episode of Thank God You're Here. My father did, and he told me he enjoyed it, and found it amusing. My father finds many things amusing, but I decided to watch it on the station it began on.
I fell in love.
Thank God You're Here brings out some of the best of Australian comedy. It brings out some of our greatest comedians and let's them take a scene and run wild with it. It is full of great improvisation, and it's definitely material for a thoroughly entertaining evening.
The concept of the show is marvelously simple: a contest gets dressed up in a costume, then walks through a door, completely unaware of what scene lay beyond. They then do their best to improvise the scene before them, frequently answering questions provided by the actual crew of the show. The costumes are great, sometimes a little bit iffy, but it just adds to the hilarity of the show.
One of the flaws of the show is it's Judge, Tom Gleisner. I can quite happily say his role is completely unnecessary, and, in choosing the winner, and criticising the contestants, he is always saying positive things - never a negative thing spills from his mouth. Rather than a judge, Gleisner appears to be what I'd call a "feel-good" instructor - because that's all he seems to actually do.
Regardless, watch the show, and just mute it whenever Gleisner speaks. You'll be much happy that way.
