Please, please, no!!

When I titled a post back in 2006 "I know - let's remake Casablanca" my tongue was firmly in my cheek - but now it seems I may have to take it out.  Well what's being suggested is not strictly a remake, but a sequel.  Just as bad though - how could you possibly follow up on what is generally considered to be one of the most perfect, if equivocal endings in movie history?  Any sequel would of necessity ruin the original. Say it isn't so.
