The spouse and PC HAD a conversation. That is auto dialog. It's bad enough I'm now forced to start out married to someone, now I have the protag talking without my say so. It is complete garbage, this is not Fallout. This is Todd continuing to show how little he knows about the series, and if the story they really want to tell is this cliche and cringeworthy with more family crap, then I'll be happy to just ignore it and have fun int he world because I can clearly see I'm not going to have a FO1/2/NV experience here at all.
You've seen what of the story? The prologue, an intro with some interaction, meant to make it MORE immersive than just plopping out a vagina and looking at a computer screen to determine how you look like. So you get a backstory, one which might actually be fake if the speculation about you being an android much like A3-21 is correct, and if you don't like the backstory well okay. You don't have to. But you've seen nothing else about the game's story. You have no idea how the game will handle said backstory, how important it would be, if it's getting subverted lateron or if the game world will even reference it past the game's intro.
Calm down, if you kneejerked any harder, you'd be making backflips!
If you don't like what you've seen so far, then don't buy the game at launch, wait for some let's plays and look if what you see keeps disappointing you. If yes, don't buy the game and be happy. If no, buy the game, cringe yourself through the start and possibly have fun with the rest of the game.
