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.
YMMV: Makai Senki Disgaea
Broken Base: Let's just say that opinions on the anime differ drastically.
Hilarious in Hindsight: Maharl claims to be Krichevskoy's daughter and Laharl's sister and is planning to take the throne. Fast foward to Disgaea Dimension 2, in which Sicily, an angel who claims to be Krichevskoy's daughter and makes an attempt to take the throne from Laharl, is introduced. Unlike Maharl, however, Sicily is Laharl's sister.
They Changed It, Now It Sucks: Part of the problem that many had with the anime was that it's original trailer had far better animation and seemed to be a lot more faithful to the game, even hinting that Baal would appear. The final product was sadly plagued with Off Model animation and while the general plot was the same, there was enough changes to put off several fans. The lack of any real fight scenes only served to hurt the anime.
