The first thing that I want to point out is something that was confusing for me, and will likely confuse your audience as well. The opening statement and opening paragraph specifically mentions dystopian "texts." No problem there. I know exactly what you are talking about. "1984," "Brave New World," "Hunger Games," "The Maze Runner," etc.
My confusion arose immediately when I read the first line of the second paragraph. "The Maze Runner is a film. . . " The opening paragraph makes it clear that your speech is going to discuss texts. Why do you switch to film discussion? If you want to focus on texts AND films, get rid of the word "text" and switch it for "story." That will allow you to focus on the book and film interchangeably.
2nd critique: The first paragraph ends by stating that you will begin discussing the "theme of persistence and bravery." Cool. I like that thematic concept. I was thrown off though when that theme wasn't discussed until the 4th sentence of the second paragraph. I would eliminate the first three sentences. They mainly repeat what the first paragraph established. That also allows the final sentence of the first paragraph to function as a great transition statement to the second paragraph's main idea.
3rd: Good job signalling your audience that you are closing. "In summary" is a good verbal signal. Conclusions are hard too. You want to summarize without repeating. I have a warning about your final sentence though. You wrote "when viewing similar texts." My concern is that at no point does the speech discuss similar texts. It focuses on only "The Maze Runner" story. Either discuss similar texts in the speech, or don't mention similar texts in the conclusion.
