I think my biggest beef is that the military people on the show do not act or interact in any way shape or form like military people.
Have they ever in a Stargate series? O'Neill made general, for crying out loud.
I remember when former Air Force Chief of Staff General Ryan was on the show, RDA asked him if he was doing an accurate job portraying an Air Force officer, to which General Ryan replied that the Air Force is filled with Colonels who act just like O'Neill.
Ryan's successor, General Jumper commented when O'Neill was promoted to general that Jack O'Neill represented everything that an Air Force General apsired to, or something like that. For that matter, I think Jumper even gave RDA a set of actual General's stars. All this is covered on the S8 DVDs.
