How could I forget? Especially with the classic line she delivered. Uh, I think it was something like, "It's a good day to die... FOR YOU!" or maybe, "I know you are, but what am I?!"
Also, while the dialogue, characters, and narrative events are completely awful, it's important not to overlook how many hits the underlying lore took. Did you like the idea of a literal battle between Heaven and Hell? Well, now "Heaven" and "Hell" are just sort of alien planets inhabited by asshole species that kind of look angelic/demonic, and their war is just a pissy territorial spat. Enjoy your epic who gives a fuck.
uuuughhhhhhh
And people sometimes say with a straight face that there wasn't that much of a difference between Diablo 2's story and atmosphere with Diablo 3's
I can't think of a more drastic difference between game sequels.
