These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Face of the Band: Asagi, to the point where people forget that there are four other members.
Narm: Despite Asagi's awesome vocal and visual skills, his performance skills are really awful at best, resulting in his horrendously choreographed, disjointed and forced pseudo-dancing, which has gained some notoriety among visual metal fans. Seriously, watch the PVs for "7th Rose" and "Der Konig der Dunkelheit", and try not to laugh while dancing along.
Tropes that apply to the game
Big Lipped Alligator Moment: In the original D, failing to reach the ending in time leads to Laura falling into her pocketwatch and a simple message to "Try Again". Apparently, this is meant to represent the mental dimension collapsing and Laura being dumped back into the real world, but that isn't communicated very well at all...
Eight Deadly Words: One of the top comments on Youtube on supergreatfriend's Let's Play was "I hate all of these characters and I want them to die." regarding D2's characters.
Narm: Some misplaced or just plain goofy sound effects, along with bad voice acting, makes some parts ridiculous.
The Scrappy: Half the comments regarding Kimberly in supergreatfriend's Let's Play of D2 are not that nice, mostly for her constant talking, redundant questions (a lot of the comments are mocking her tendency to ask Laura if she remembers anything before her Trauma Induced Amnesia), and unprecedented hatred toward Parker, who is only trying to help.
Squick: The battle against Xilo eventually becomes this for obvious reasons.
That One Boss: D2's Martha, who is constantly moving, can cause a lot of damage, and her weak point is oddly hard to hit (her violin), meaning you have to slowly chip away at her health unless you get a lucky shot. The fact never stops saying the same thing increases the annoyance factor.
