I think the problem that people have with the endings and what the game leads to is that most people probably just aren't used to being exposed to tragedies like this in media. Most stories have something to say and so it would make sense for someone to be turned off by E33's constant moral grayness and ambiguity because they are looking for finality in some message they thought the game would deliver. You cant really say the point of E33 is ___, you can only discuss what you've seen. The way I see it is that the game is just showing how a tragedy is affecting this one family while using the canvas and people of lumiere to represent the manifestation of the intense affects that grief has on the psyche. As the player I dont think the game is asking us to dissect every scene for thematic relevance, theorize this character represents x for y, etc. we are meant to simply observe. Any conclusions drawn between characters and how they affect the story is icing on the cake, because that means the game is doing its job of making you think. The final ending choices are not meant to be interpreted for what is right/wrong, rather interpretation itself is the goal. It's just meant to make you live with the tragedy of this family. Now is it perfect? No. I have my issues with parts of the narrative, but the way it just left me to simmer with the dark grayness is different at least.
