Compare the dramatic effectiveness of the relationship between setting and plot in two or three plays you have studied

The setting in A Streetcar Named Desire is purposefully used to the show the physical and mental transition of Blanche, thus her character development throughout the plot. Blanche is said to have arrived from “Belle Reve”, a place which is translated (from French) as ‘Sweet Dreams’. Consequently, she is now placed in New Orleans which is described as “dark” and shrouded with an “atmosphere of decay”. One could argue that Blanches’ microcosm, that was Belle Reve, has been shattered; such a stark contrast in setting almost foreshadows her mental “decay”. Blanches appearance is “[incongruous to the setting]”, from this we can infer that she is incapable of fitting into her new surroundings, which further reveals her inability to make a successful transition into the Kowalski household. 
On the other hand, the setting in Waiting For Godot highlights the ideas of stasis and singularity rather than transition. The stage direction of Act Two in the play states that the act will begin “[Next day. Same time. Same place]”, the repetition of “same” highlights the idea of singularity of place. The fact that the setting is identical to the setting in the previous act supports the notion that the characters in the play fail to evolve or develop further than their current state which is reflected by the repeated setting. In Act One, at the end of their verbal repartee, Estragon bellows at Vladimir "I'm going", but then we find out that [he does not move]: the characters in the play are almost trapped within the setting, they cannot progress in their lives due to their constant 'Waiting'. It is clear that whilst Beckett uses the setting to confine his characters to a life isolation and stasis, Williams utilises the setting in A Streetcar Named Desire to illuminate the development of Blanche and how her residence within the new setting, that is the Kowalski household, proves rather detrimental to her mentality.
