Next on the list is Disgaea, this might be a doozy.

Two years ago, the angel apprentice Flonne was sent to the Netherworld to assassinate King Krichevskoy, however she appears to have been beaten to it as the castle is on fire and the King appears to already be dead, instead she finds Laharl inside of the King's coffin who is also the King's son. Flonne gets dragged into Laharl's mission to reclaim the Kingdom along with his subordinate Etna and an army of Prinnies who are demonic penguins controlled by the souls of sinful humans. Along the way they run into a space captain and his motley crew of sci-fi homages as well as Flonne's employer and a charismatic demon dubbed Mid boss. All the while Etna is plotting a takeover of the Kingdom and Flonne tries to teach love to Laharl.
Now I'd never played Disgaea before this but this isn't how I envisioned it in anime form, now I heard there were lots of drastic changes before production but what we had was not good. The characters are annoying, the dialogue is annoying along with the dub, the story is bland and doesn't really go anywhere and it feels like a kids show, I just really didn't like it and even though I do own the DS remake of the first Disgaea game I feel reluctant to play it because of this anime.
Not a good advert to get people to play the games.
Final Verdict: It behaves like a 4Kids show and has the cheesiness to match, I really hope this isn't what the game is like otherwise I may never play it.
