Good stuff. I think you're dead on in your assessment of SH2, and, while I haven't played any of the series after 2, the fact that they seem to be shoehorning Pyramid Head into every game after it sounds pretty stupid to me.
I hate it how some franchise are milked for more money long after they've played themselves out (I'm looking at you, Nintendo). Every gaming company should have a placard in every office and cubicle reminding them of the great Fawlty Towers rule: "Quit while you're ahead. Always leave 'em wanting more." If not that, then at least leave well enough alone when all the loose ends have been tied up.
