You should consider yourself lucky. Do you remember the few times where it lasted two weeks? There have been memorable things that happened. Nelle slashed BLQ at a Nurse's Ball and then that one year someone was found hanging from the rafters. This would should be interesting with two secrets exposed. One will be Gio's parentage and the other might be Drewfus exposing Portia and/or Nina.
I think it could be better if they focused on talents other than just singing. Magic acts, martial arts, pet tricks etc. But most importantly, I think they should lip-synch. The actors are not professional singers so it shows that they can't do the choreography and sing well. Lip-synching would solve for that.
Last but not least, bring back the chorus line. It was a good show stopper. Perhaps Lucy and Olivia or Lucy and Tracy could be the new Katherine and Lucy.
