I Need To Get To Know My Relatives

I have to find a DVD for my 14-year-old niece who – unfortunately – I have never met. In fact the only contact I ever made was when she was on the phone at my parents-in-law and they put her on speaker.
So, my husband made a deal with her that she would watch an entire movie in English and as a reward she would get a DVD of her choice. Her choice, as it turns out is to have us choose. This, as it turns out is putting all the difficult choice-making on me. Yeah, thanks a lot. Can I give her „While You Were Sleeping“, because that’s what I would probably have liked when I was her age. Only that was more than ten years ago, so she probably has seen that movie on TV, maybe more than once.
Can I give her „Sense and Sensibility“ or is that considered a boring movie by kids of that age by now?

I have no idea what to give her. I don’t even know her. Plus, I might not be the best person to choose anyway, since I was running to see old French movies when I was sixteen.

Any helpful ideas out there?
