^I wouldn't be interested in a remade B5, not at all. Not because B5 as it is is sacrosanct, it's just that it wouldn't be the same show at all if it were 'Battlestarred' as you say. And I'd drop it, just as I have BSG because of its unrelenting grimness and lack of character development.
There really isn't any one episode of B5 that didn't have arc material in it at all and even if they served no other purpose, the stand-alones made the characters more real to us. Material in them would often telegraph something coming down the road (another beef I had with BSG-stories coming out of nowhere).
