Help with essay topic- opinion on Huck Finn?

I have to write an essay about my opinion on Huck Finn. I have tons of information about it being a clic and what i like about it, but i want to write something interesting. I was thinking on talking about Mark Twain's literary devices, but what should I talk about. What were some of the specific literary devices he used to get his points across. If there are any other opinion related topics on Huck Finn that sounds interesting, please post it here. thanks.
