Does the show need an injection of life, if so, then what?

H&A has never seemed to value its history, so it makes sense that they rarely bother acknowledging milestones.

The show seemed to embrace and celebrate its history in the 2000s with Sally's non-wedding, Summer Bay's bicentenary, Sally's farewell and Alf's 60th bring people back.

We also had a number of characters back for Sally's wedding to Flynn, Lance's frequent appearances and other characters like Pippa, Carly, Floss and Sophie back for the visits outside of the mass returnee events.

Most of those events didn't line up with a milestone though except for Alf's 60th.

It kind of makes sense that past characters from the first 20-25 years rarely come back these, since they are mostly irrelevant now except for a handful that were closely connected to Alf, Leah and Marilyn.
