just finished it, why do people hate it so much? I thought it was nice, pretentious? absolutely, poor exposition? from the beginning, but once you start getting invested in the game and things start to make sense both gameplay and story wise it's hard to put down

People didn't like it because it was essentially a walking simulator with the game play only being go from point A to point B. They were hoping for something a bit more, at least a little more variety.

People expected something else. Mainly because it was from Kojima.

It's basically mail man simulator with a twist. Sure you run from enemies and what not but the biggest part of the time you're just walking/riding/driving with boxes that you deliver.
Apart from that the cutscenes are very long which may make people feel like theyre not really playing a game.
