Falcon Lake

This is obviously based on first hand experience. Without spoiling anything, the basic setup is, as stated in the official storyline, that there is a 13-year-old boy (going on 14), who bonds with a 16-year-old girl. The age difference is almost just 2 years, but we can imagine the difference in their maturity - and we will be right.

The male audience already knows where such a setup can lead for a 14-year-old boy: both Heaven and Hell. And usually it leads to both - almost without exception. So it is a really hard watch for any male who has not completely forgotten his early teen years. Pure art here.
