At that time and perhaps today, movies gave a moment of escape from the reality of life. Personally, I enjoy the brighter perspective. I would expect a happier tone from films because life was difficult and people need something to hope and dream for. Since this movie was post-code costumes were more elegant and the women were left with a little more clothing on at the end of a number.
Re: Rose Marie-What I observed in this movie and what draws me to movies of the 30's-50's is the banter of dialogue. I think post code most of what was happening between men and women was relayed via clever dialogue, which takes great skills from writers to carry a story. I must admit, my clearest memory of Eddy and McDonald is the running reference of the two doing the Canadian Love Song. I intend to view the Rose Marie in its entirety.
