Review of Two Guys from Milwaukee

I enjoyed the playfulness / innocence of Dennis Morgan &Jack Carson. They meet, get drunk, and fall into bed together---but this is 1946 & it's all OK ( even Carson's sister says that he brings strange men home all the time}. I thought that the writer of the screenplay gave Joan Leslie a rather confusing role. She's Carson's girlfriend--but he is Only a taxi driver & doesn't earn enough money--so when Morgan comes along she seems to immediately fall in love with him--and he with her. Later, when Carson gets rich,she drops Morgan & gets back together with Carson--who she had treated pretty awful. Is this romantic? I felt very annoyed with her character &was disappointed with the movie.
