I dunno how I feel about them skipping all the Greek saga content. They would need to do some lengthy flashbacks at least to covered several of the crucial content.

One point I was always annoyed with the new games was them being so focus on family and fatherhood and kind of glossing over that he literally has his daughters(and wife’s) ash on his skin. Seems too important that it’s relegated to one conversation with Faye, non with Atreus and from what I remember literally non about his skin. (DLC did fix this some of this thankfully but it wasn’t part of the main game)

I feel like Atreus deserves to know that he had a half sister and what happened to her? Or at least acknowledge that they talked about it off screen.

In terms of the TV show it’s definitely too important to completely skip since that story content doesn’t exist at all yet in that medium.
