I don't want old characters showing up just to die...
Thank you both. I despise this sort of lazy, low-rent writing. "Need ratings? Need drama? Kill someone! Make them hate each other! On tonight's show a major character will die because we don't have the imagination to do it without snuffing your beloved characters."I really don't want a Star Wars movie that explains that after Jedi everyone had a falling out...
But I liked Dennis's point that the masses are not going to tune in to see a retread of TNG or any others. It needs to be different. I think that means excluding the possibility of involving previous Trek characters in the plot of any episode. Passing references to history are okay to provide context. But even that depends on the events of the new series happening during or after what we have seen so far.
