(Spoiler Free)
I have completed the game in 38 hours. The graphics is one of the best I have ever seen. The sound design is superb specially when in combat, it gets you pumped up. The sound the infected make is also terrifying. The game play is so grounded and satisfying and also brutal (Bursting head, flying limbs, stabbing in the neck). The way how naughty dog presents the story is great in my opinion. Naughty dog made the characters like normal people in the real world, capable of doing things or making decisions that are agreeable or disagreeable, good or bad, stupid or not stupid.
There are people that hated this game due to things that the developer made them do. In my opinion those people are just upset because of there emotional attachment to certain characters. Their attachment is blocking their mind and failing to understand the sides of other characters.
