"Why can't I just shotgun blast this door open, this isn't fun or realistic." - derp

Like it was explained before in this topic. His problem with it is the game shows earlier that you can open a door with timepowers, later you can't.
Personally, I found that example not good too. But the fact you can't climb a truck the same size of one you cán climb (in the same area nonetheless) is jarring and bad level design. QB is quite full of these examples. You can get on a van, but not on a dumpster. You can climb over a wall higher then Jack, but you need a box to stop on to get onto a container of the same hight, etc. A game like TLOU never introduced as mechanic to later take it away for the convenience of the game director. No, they stick to their guns. There is no moment in TLOU where you blast open a door with a shotgun, only to not be able to later. Thàt's what he means, and that's a fair critisism.
You also talked about the show and how he is 'wrong' you don't meet characters until later on, while the show for a great part revolves around that annoying hacker dude you don't meet later on. Yes, you meet that bloke with the pregnant wife earlier. So what? Even he barely plays a role in the story of Jack. He found the show cheap looking, badly written and unnecaisary, and I can't say he's wrong with that.
I get it, you liked the game and you're right to do so. Just as AJ didn't like it and is in his right to do so. No need to get all worked up about it.
