See, I love - adore - the tongue in cheek banter, but I prefer it with a slightly more serious plot. Not necessarily really heavy, but of the show's plots, I like the serious ones better, so I like fanfic that takes a more serious tone (still leaving room for banter and some ironic humor regarding the situation). But I think I understand the desire to take these guys and put them in serious situations. Granted, it's not the tone of the show, but I admit I like it (when it's not overdone. Too heavy, too dark, and, yes, it loses something of what I love about the show).
