I loved The last of us part II. I think that the people hating on this game don't really get it and maybe it's just not the game for them.
Some people just don't get what it's about.The last of us part II is a game that realistically shows how humanity went rogue from an apocalypse and started turning on their own kind because of the trauma the cordycepts infection caused them. Some don't have empathy anymore wich is realistic.
SPOILER
I think that the people that don't like The last of us part II got too attached to the characters and we're disappointed by the fact that Joel was killed, therefore they had a hate for the game from the start.
NON SPOILER
Personally I believe that every single part of this game is realistic (minus the glitches of course). From the story not being a light-hearted, jilly jolly, boring game to make all players enjoy it. Its dark. Real. Emersive.
Also the graphics are amazing. The attention to detail is also amazing. The separate stories you can find out about (like from npc's in the game talking to finding letters about one's story) is realistic and there's more too.
Overall I think it's the PERFECT game for the right people and very enjoyable on light or hard difficulty.
