Actually the average moviegoer does give a toss about the original characters. They are what people actually remember about Star Wars (interestingly mostly people just seem to forget the prequels ever existed and key in on Luke, Han, Leia and Chewbacca et al). No doubt that came up in the inevitable market studies Disney/Lucasfilm did when deciding how to do this film. Once they concluded they needed at least part of the original cast the time setting was locked in pretty much.

And yes the quality is very uneven. The Thrawn Trilogy was quality. Dark Empire was rubbish and New Jedi Order was uneven to put it mildly. A lot of the blame goes on Lucas and Lucasfilm for claiming to be guarding the integrity of the story lines when in reality they did not (which became ultra clear in the prequels). This guy on Ars Technica goes overboard in his glee on the decision but he has some points:
