First of all, spoilers? Any article like this should have a BIG DISCLAIMER that it contains spoilers. Not everyone has played the game!
Secondly, the author completely misunderstood the story of this game. Last of Us 2 is even more about the story than the first one. You could even say the first game didn't have any twists and turns, it was a pretty linear experience.
The second game, however, has narrator switches, flashbacks, fast forwards...
The CEO of the company said "The first game is about love. The second one is about hate."
People aren't black and white beings. We doubt ourselves every day, we reconsider our decisions very often, and sometimes even we keep doing things that we know are wrong, or are useless and won't help us. The first game has very little of this, but the second... it's a masterpiece of the human psyche.
I recommend playing Hellblade: Senua's sacrifice (sequel coming soon) to see another game that invoques negative feelings in the player, yet it is still awesome.
Get over your grief for Joel. Just take the story, and you can dislike it, but it doesn't mean it's bad. We all can dislike good things, but denying it's good just puts us in a permanent state of denial and we never process our grief.
Also please, ntbcheck, add there a spoiler disclaimer.
