Quick! Let me know is my thesis statement is doing it's job!!!?

you should shortened your thesis statement....how about something like this -- "Tomson Highway's use of the Ojibwa does more than make his play realistic, it sets the foundation for the journey into cultural collision." Then you can make the rest into a supporting sentence, like...."A collision of tradition, "white" values, and attitudes within the lives of seven women in the make-believe Wasaychigan Hill Indian Reserve in Manatoulin Island, Ontario."
