Love the videos, but I must say I have a different inturputationof the GOW games.
Spoilers of course
I never got a redemtion vibe from the first game. I got the impression more of hubris in that Kratos felt that he could escape the guilt of his actions. He hid it through violence so that the gods would find him worthy enough to remove it. When they didn't suicide was his option of escape, but that too was denied him, so he lashed out at those that kept screwing him over. When they tried to reign him in, he lashed out harder.
This doesn't exactly make him a likable character, in fact we may resent how much we might see ourselves in this behaviour. That's what myths and ledgends served to provide beyond origin of the universe stories: literary examples of how behaving badly leads to a bad end. Immature, yes., but how many of us thought out parents were just being mean for grounding us, that our teachers gave us poor grades because they hated us, or that sometware companies put in anti piracy codes out of pure greed. It can never be we did something wrong. We want freedom from the dreaded authority figures that want us to behave.
This doesn't save GOW2's story as there really wasn't much there on its own. It doesn't even really resolve and instead of trying for any kind of message they go for the "uber cliffhanger" ending meant to wet the appitite for the sequal. GOW3 I'll admit had more than was needed (but hey, the game needs levels, and it's not as though greek myths weren't without side stories not necessarly imporant to the overall moral of things) and much of pandora was put in to put greek myth back on track (whereas the first game ingored it for everything but names). Pandora herself was something of a cheap shot as well, offering us the idea that Kratos might be coming to his senses before finishing the blind rage again. As for the first person, I think they were trying too hard for that "personal experience". To make the character Kratos less an avatar and more us. This isn't pulled off well often, but it sometimes works, like having to ppush the button to kill The Boss youself in MGS3 despite it being presented as a cutscene.
Then the end, well, any discussion of GOW's story is incomplete without at least trying to interput Athena and her actions. She at least implied that she'd been guiding this from the start to her own ends (get rid of the gods and their earthbound legacies to take over herself) leading me to wonder if the whole trilogy was the greek tragedy, the first game searving more as porlogue. We will probalbly never know the reasons behind Kratos' (attempted) suicide but this is who I see it. He lashed out at the gods to be free of them and their manipulation, only to find that that had all been him being manipulated by another god. It fits the tragedy pattern of the guy on top taking actions that lead to his downfall, at least in the sense that he didn't get what he really wanted for all the damage he did. Athena could and would use him again as she built her new world. In the end he takes the way of more than a few greek tragedy figures (death to escape the damage he did) though much of me thinks he did it just to say "fuck you" to Athena.
I won't claim things as art, but I don't write off the third game either.
