Book Reports / Paired Text essay on Nineteen Eighty-Four and Brave New World... where to start? [3]

One of the most important pieces of work for the entire year where I am is a Paired Text essay, where we choose our own two texts and our own focus/direction. As the title suggests, I've chosen the classic pairing of Brave New World and Nineteen Eighty-Four.

I know I'm going to focus on the dystopian aspect of the novels, and HOW the authors warn us... or something along those lines... but I'm kind of vague on a direction and which techniques to talk about (in these essays, there is heavy emphasis on technique and HOW the author achieves a message)... it has to be 2000 words, and our best writing, so there has to be a good amount of solid content.

Some ideas I already have but can't really find a direction on...

Family made meaningless
Sex made meaningless
Setting used
Winston/John are us in the unfamiliar world

And the big difference...

BNW controlled by joy, contentment, satisfaction
1984 controlled by fear, hate, oppression
>Contrast of feelies vs. two minutes hate, lots of sex vs. no sex at all

Any help? Thanks in advance.
