Tennessee Williams chose themes in "A Streetcar Named Desire" which were quite controversial in his time (1911-1983). Homosexuality and mental illness play important roles in this play, and they are not hidden, albeit they are carefully mentioned.
The story was controversial in that time and even until today there are some stigmas and taboos about. This play doesn't really help in understanding them; it seems to me to be more like some kind of morbid entertaining value.
I also didn't really like the characters much. Blanche was so annoying and obnoxiously self-centered and haughty. Stanley was kind of cool, but then he became so violent. Mitch and Stella were nicer, but their characters were much more flat.
Reading pace and writing style were pleasant.
