Re: 1 new cast member who saves an established show?
Heather Locklear on Melrose was the obvious example. There aren't many.How were the ratings for Happy Days in the first season? Remember, they replaced Pat Morita with Al Molinaro at the hangout (Al's/ Arnold's). I don't think that was a case of saving the show though.
I wonder whether any of the Doctor Who actors fit the criteria. I'm not familiar with the show's ratings history in the UK.
