I'm somewhat loathe to be get back into this discussion given its polarizing nature, but you wrote something that seems so obvious, but perhaps has, in fact, been totally ignored by many.
Reviewing what was shared with us in this thread shows that every time they followed what the GM, through the NPCs, put forth as the way the PCs were destined to go got them deeper and deeper into trouble and danger and what culminated was them all trapped in a "cool room" of a diner with death all around and yet another NPC trying to call for a vote to yet another plan from the GM, through the NPCs.
It seemed to me that RR had been pushed to the tipping point by the GM. At every important instance, the party has been led into a deeper and deeper pit. A key moment in RR's story is when he says the NPC's at the diner inexplicably dropped their guns and got munched on. From RR's perspective, he is baffled by this NPC behavior. Finally, in the cooler, one can imagine that RR realizes that the NPC's are simply the pawns of the GM (and not acting like real people) and they maybe part of the problem, not the solution.
When RR watches the show, he's frustrated by the stupidity of the people on the show. Put two and two together and you see the GM trying to cultivate this experience which is an assault on RR's intellect and survival instinct as a player. RR admitted that he could have done it differently, but it's not hard to imagine that
in the moment RR perceived the NPC's as the biggest threat both as decisions makers in-game and as tools of the GM to manipulate and frustrate the players.
As others have suggested, had RR been familiar with the genre, maybe he would have just tacitly accepted what he viewed as detrimental actions by the NPC's. But RR is expecting to be able to act with freewill, not according to characters in a script.
Let me repeat something you wrote, essentially speaks to something that is crucial to the way I perceive this and seems to be irrelevant to many:
...it stems from the apples to oranges comparisons we all are making between fiction and game.
I've always considered An RPG as a game, not a fiction. Everything about what the GM was doing feels like a fiction being dressed up as a game. As I said before, I think many GM's in this thread latch on to the part of this that resembles a disruptive player they've had to deal with and they are focused on RR as that guy.
The flip side is that I can see more of why the GM was annoyed. I suspect the GM wants an RPG where the players are, in fact, pushed around and not allowed to necessarily solve the problem. Several people have said that TWD is not about the zombies. In essence, TWD characters are never allowed to extricate themselves from the zombie problem and they are discouraged from confronting it. I can see how someone not familiar with this type of RPG would be frustrated very quickly once he felt the GM was using the NPCs to further stress the party.
just thinking out loud with those last paragraphs...
