I never got the emo nostalgia outside of just being nostalgia. While they were from before my era, I can just tell they were extremely fucking annoying and whiny. They're also not very hot either. Maybe when a girl only wears black is neat, but emos range from looking like anonymous asexual but black to looking like old christmas trees. I also wonder why they were the most shrekscoped of all fandumbs considering furries and bronies are far cringier than other fandumbs.
