I can't remember where I saw this (maybe it was on this site on another thread) but MASH could be divided into two eras — the Wayne Rogers/Mike Farrell without a mustache era and the Mike Farrell with a mustache era. The first one went for laughs, the second one became too preachy.I agree that Trapper 2.0 wouldn't have worked, I just thought BJ was a bit of a drip.
