My idea is for them to actually deal realistically with the series concept they introduced. They took the easy way out; they practically ignored it.You're idea of "exciting drama" basically is the same as saying "toss out continuity and canon, it'll make things better".
They did, it's just that they didn't fall to pieces or let things get that bad for themselves in the process the way so many other stereotypical "lost people" stories would have it.
