It's ok to have outlier opinions and a lack of patience. Some people probably think The Godfather or Shawshank Redemption are too slow as well.
At the end of the day, not everything has to be constant shoot shoot bang bang or hack slash hack slash, sometimes it's good to just slow things down and let it breath.
Hell, TLOU does those slow walk and talk moments better than most, since not only are you generally simultaneously scavenging for parts or supplies, but you're also soaking in the atmosphere, art, dialogue and fantastic character building.
I find a lot of people can't look past slower exposition and walking or soft puzzle segments, and others simply aren't very good at the combat, which then skews their notion of the gameplay as a whole.
The actual combat and encounters in TLoU are some of the most satisfying and well designed in the entire third person shooter genre. The controls, gunplay, feedback, level design, fluidity of animations and dynamism of approach options (guns, explosives, traps, stealth, contextual melee, bow, environmental objects, cover system, on the fly crafting etc) are unbelievably competent, polished and rewarding. I can't even take those who say the gameplay is bad in TLoU seriously.
