I just don't want it to get stale. At the moment, they have a lot of mysteries, and a lot of them need to be solved.
If they can get to Earth with a cliff hanger at the end of 4, and then maybe earth/galacticans defeat the cylons by the end of 5, or maybe the cylons wipe them both out.
I'd like to see the writers be as mean and gritty as they have been known to, and kill all the humans.
I wonder if they are going to bring back Buck Rogers...
