Since I bought the ps4 I cant claim the most prestigous taste but wasnt last of us just one step away from being a walking simulator and a boring, cliched, bad, one at that? i Remember trying Uncharted years ago since everyone was telling me how great it was and was bored five minutes in.
+ The story is great.
+ The characters are very well done, not just the main characters, the side characters are also fleshed out and interesting.
+ The stealth part is really fun, and it's possible to ignore a majority of enemies by using it.
+ The world/atmosphere is amazing. From sneaking through apocalyptic cities while dodging scavengers, to running through forests, watching the wildlife.
+ The Graphics are great.
+ The voice acting is superb.
+ The gameplay is fun and satisfying.
+ The change in scenery (Summer - Autumn - Winter - Spring) is beautifully done and feels very real.
+ The ending forces you to really think about your choice.
- The 'zombies' can get a bit bland at times, it's not that bad as you face other types of enemies.
- The start can be a bit slow.
- There is a place in the game where they force you to change character for a while, some people love it others hate it, I enjoyed it.
- If you're going to go guns blazing and ignore stealth, certain parts can get a bit long.
- There are parts of the game where the difficulty spikes.
-/+ There are bosses that require stealth and brains to kill.
- There are many cutscenes, but they're all interesting and well done, nothing like Final Fantasy X where you're playing a movie.

You mentioned in your original post that you brought The Last Guardian for your woman. I played through The Last of Us with my girlfriend, and I think she enjoyed it even more than me. Metacritic (95 /92 user) is not wrong in this case, it is a 9.5 game.
