Babylon 5 demonstrated that you can keep absolutely everything else crappy (effects, costumes, heck acting and even cinematography), so long as you're good at conversations in rooms.
I don't think you understand the appeal of Halo if you think it can be about people talking in rooms. Halo would have to be something far more complex, like Band of Brothers.
