Here is my take on GZ:
Every Kojima game so far had horrible and cringeworthy writing. Seriously. But it always seemed to fit cause the MGS universe is so damn stupid. The bad writing and insane things that happened felt like such a sharp contrast to the times the game pretended to be serious that it almost always worked somehow, in an insane way.
GZ just seemed waaaaaaaay too serious so the horrible writing stood out way more despite fitting the tone of the game more than in previous games. I don't even know how this is possible.
I hope PP will be a lot sillier otherwise I don't know if I can take Kojima's pseudo philosophical garbage.
