It honestly depends how you look at it. I think as a pure game, it falls a little short, because it is so linear and fairly limited in the gameplay department. A good chunk of it is a cinematic experience, and I can see some people docking it some points, simply due to the fact that you watch a good portion of it, instead of playing it. The gameplay, as I said, is linear and limited. At it core, it's a fairly simple. In comparison, I would give a game like MGSV higher marks in the gameplay department because it's so much more robust, and the possibilities are endless.
That said, what TLOU does, it does extremely well. It's got a good system of stealth and action gameplay, and the mechanics are all very tight and robust. The nature of the gameplay also changes depending on the difficulty setting, and at higher difficulties, plays like a true blue survival horror game, where you must consider each scenario very carefully. If you don't like that, well just play it as an action game on Normal. It's got a sweet spot for every type of gamer. Couple that with what most people believe is one of the best stories ever told in a videogame(albeit subjective), and it's a recipe for a true classic. On top of that, you get a pretty decent multiplayer mode as the icing on the cake.
So yeah, if you don't care for it, I'd think it's just not for you, because it's damn hard to criticize from an objective standpoint.
