I can absolutely understand not liking The Last of Us.
Its status being constantly heralded as "the defining game of its generation" is, IMO, utterly ridiculous. The Uncharted games have definitely gone through an unflattering reevaluation in recent years, and I think it's time for TLoU hype to get the same reality dose.
Still a game that I enjoyed a lot, mind you. And obviously an exciting prologue (I feel like half of what I read about it is people who just played the prologue ...).
That's silly to assume most people have only played the prologue. I've platinumed it on both PS3 and PS4, probably 5 playthroughs total. I've put countless hours into MP - more than Socom or Counterstrike, my two previous 'most time played' games.
It's phenomenal. Everything about it. People here know I don't give two ducks about the story of a game, yet TLOU managed to pull me in and make me care about them [that -never- happens]. Combat is fantastic - early on, the lack of skill with weapons makes headshots hard, which makes every bullet in that revolver count. As you upgrade, you get better, and eventually you're taking down enemies much easier. They also perfected in game crafting for an action game.
The only two big 'flaws' [and they're minor] is, as someone else said, some midgame pacing before things really kick into gear, and a few too many 'move the box' puzzles. The first is easily excusable due to how masterfully the rest of the story played out, and the second is just the hit you take in a new franchise -- there is only so much time to code, and so sometimes you'll see them have to reuse a puzzle mechanic since it was already developed rather than add in unique mechanics every time.
Maybe it's age related... I can't stand the high school drek of, say, Persona 4 [despite loving drpgs and the SMT press turn system], and literally cringe as I speed through dialog. On the other hand, I've got kids... and completely identify with Joel and love every character arc. As I just mentioned, the ending is pitch perfect. It's the only possible ending. It's exactly what Joel had to do.
