Why should anything remain true to the original.  Of course producers want to introduce the concepts to a whole new generation but the original conceptual thinking has completely disappeared.  BSG producers and writers grappled with how to reintroduce the franchise to a new sophisticated generation of Sci-Fi watchers.  It was novel and refreshing, no longer treating the viewer as mindless imbeciles.  We need to be entertained but also be intellectually stimulated, a feature that is sorely missing in today's movies and TV shows. 

Forbidden Planet is being remade, and I ask why.  Harlan Ellerson was once approached to write a screenplay for the remake.  And his response, and I paraphrase: "It was made right the first time!  Why mess with perfection!"  And I agree.
