The structure is good, the show has been funny in the past.
Mel B and Tim are still good, Titus O'Reily was excellent when he appeared.
Mel T needs to do some real work and find some genuine funny subjects instead of the rubbish she has come up with lately, she has the ability to be excellent.
Maybe it is the writers that are no good?
Why not get some advice from Shaun Micallef, he is arguably the best comedian around, there are so many good Aussie comedians not seen recently, Rosehaven for example.
Arj Barker another and there are many many more very good comedians to choose from.
Get some of them on, the sports guys have been absolutely hopeless recently, very poor jokes, unless you just want to appeal to 12 year old children.
Cheap Seats please pick up your game, you could be good.
