Glass Menagerie Reflection

This is a reflection on the Glass Menagerie.  I wanted to ask a few questions concerning this play that we read in class. In my opinion, although it may have been an accurate representation of what the 1930's were like during the Great Depression, I feel little interest in the story. The story in all had complicated metaphors and double meanings surrounding it, however; the story is unexciting, and rather boring, in reality it is a story about a man and his hysterical mother accompanied by his socially awkward sister.  The story I think accurately depicts the time period while showing what a family of the time may have had to endure and what it may have produced.  However; If there is another item of severe importance that I am supposed to grasp from this story, then I do not.  The messages in the book remain unclear to me as well, in the end Tom ends up leaving his family and roaming the United States while his family stays in their tiny apartment.  This play shows a sad family in an extremely unfortunate situation which draws a lot of empathy and sympathy for each individual character, however is that all I am supposed to feel? What emotions are trying to be evoked from me besides just me feeling sad for a family that breaks down.  The message that is supposed to be there, I am afraid is not visible to me.
