The problem with the Trek franchise after DS9 was that it became so formulaic and relied too much on techno-babble and "reset button" solutions. None of the characters ever changed or grew, nobody ever died permanently (except a MACO, like anyone cares).
That's why I like the new Battlestar Galactica. I haven't heard a word about how the ship works and I DON'T CARE. Show me interesting characters and I'll tune in.
