I think that before people take the time to comment on something, they ought to get their facts right. The play did not take place in the 60's, but rather the 50's. Lena was the Mother, not the Grandmother, and Walter was not a drunk, but got drunk now and then. If you had any concept of history and the context of civil rights in the 1950's you might have gotten something out of the play. But in todays world where young people expect everything to be given to them and don't know the meaning of what it is to struggle, I can see where this might have been over your head. If you would have listened to the words instead of waiting for something exciting to happen, you might have seen something you would have enjoyed.
