I watched most of this film the other night, and plan to catch up with the rest of it.
It is an extremely disturbing movie, which I found gripping, but difficult to watch. It is well written, well directed, and very well acted, but almost relentessly sadistic. It is obviously meant to provoke, and it hits it's target square on. This is not the movie to watch if you are looking to simply wile away a few hours and relax.
But, Gamemaster1967, the character played by Ellen Page is not a victim of sexual molestation (or a victim of anything else), and there was only one adult male character (played by Patrick Wilson) who is presumed to be a pedophile. Most of the tension comes from the fact that this is a two-character drama, that takes place in rather confined quarters, and involves a monumental power struggle between those two people.
