The insufferable Fatigue status is ALWAYS popping and forcing you to the arduous work of resting, that includes never used before rations, hunting and stuff that, again, just ruins the game further. Nobody likes rest, no one actually uses complex resting mechanics in the tabletop game. Whoever developed this, i'm sure never played Pathfinder before.
The late game, at level 15+ is absolute horrible. Creatures with Armor Class of 63, everything damages Str, Dex, Con or drains your levels. You have to constantly reload to pass skill checks of 40+, you miss treasures, events and even locations in the map just because of the ridiculous high Challenge Difficulty skill checks. No d20 game should go as far as this, the late game is just a mesh of high numbers and hit-kill spells.
The Kindgom management system ruins the game. You will spend a vast amount of time dealing with annoyances from everything around you with the most overcomplicated, boring and unecessary system imaginable. The game completely change, and the feeling of a good rpg adventure is lost. Now is just a chore. Dozens of events, keeps poping while you try to explore or resolve other stuff in the game, random stuff happens and you lose events. Your advirsors need a unreasonable amount of time, months and months to solve anything and, in meantime, more stuff pile on and can even fail tyour game, because of timers. With that you will have bad quests failing because you have to deal with other stuff. And this is core gameplay, this kingdom management simulator is a crucial part of the game, and I can't imagine a dev making it worse than this one. This point is the sole responsible for the vast amount of negative reviews, and with reason.
And the ultime disrespect to the player: The game remove your companions near the end. You pass through one of those old cliché "you must find your companions (because they conveniently got separeted) and you witness villain talking to them". And just like that, you can't use some anymore. And you are done for if you made your strategies around using those, like I did by losing two of three casters in my party. A disrespect to the player, the removal of crucial pieces just because "its fun". And its not even with good reason.
The final battle is a huge chore. This kind of mechanic no one should use in a game where casting is limited uses per day. It reforces the idea that the devs don't actually play tabletop Pathfinder, in order to create such a bad showdown
