Move along, nothing to see here.
This is a very interesting take on the scenario of an outsider wandering into a bad situation. In most games we'd be forced to get involved (and it looked that way after the gate shut itself behind us), but... no. It's none of our business, we're just passing through. The entity responsible for the weirdness, while alien and not exactly good-natured, is non-violent and not our enemy, and it wants us out of its hair just as much as we want to be gone. The whole thing feels refreshingly reasonable.
Is this what Silent Hill is like for everyone else?
