Yeah, I hated the shower scene. At least in the series Houlihan got to be more of a person, especially after they ended the double act with Frank Burns. She ended up being pretty sympathetic. I think we met her father, who was a real hardass officer, so you realized that she was always trying to live up to him and failing.

Don't recall any episodes with gay or trans characters (not counting obviously straight Klinger), but I think it might have been handled sympathetically.
