I think it depends how you play to be honest. Many of us have mentioned that Syria is poorly designed, but looking over some of these other videos, I can't help but feel papercuts is complaining because the game isn't easy enough, or that he can't get away with playing recklessly.
Why on Earth would you start melee'ing an enemy out of cover, whilst there is a turret shooting at you? Did he really expect to be able to pull off a melee fight in that scenario? Either run away whilst blind firing behind you, or jump in to the sea to find a better approach or new cover.
In the video after, he literally ran straight in to a group of enemies, expecting any other outcome other than death is a bit silly.
The one after that, the reason the enemy didn't die is because aside from missing several of the shots, the ones that did make contact hit the enemies shoulder and hand, which weren't enough for a kill. I do agree that it's utterly stupid the guy didn't flinch. The hit reactions are the biggest issue.
The next video, where he's shooting the laser enemy at a distance, the reason it's not making contact is because he's not aiming well, at all. There's this thing called recoil, and in Uncharted it's pretty realistic. Instead of firing continously with the reticule bouncing all over the place, stop shooting, let the recoil subside, and patiently aim for the head. Not that shooting a guy in the head with a pistol at such range was going to be easy in the first place.
I agree with some of the complaints, but I think Papercuts post is great in that it also shows many issues are simply down to user approach and/or error. Hate to sound rude, but he's just not very good at the game lol.
