Honestly, I think you're exaggerating a bit there. I personally had a lot of fun with the story this route is following and really enjoyed the lore pieces that were added; the fact that it has more serious and dark themes brought more depth to the characters from my perspective, which made me like them even more. So, yeah, I think it's more a matter of personal taste, so I don't think it's fair for you to claim that the things added in this new route are unnecessary.
