Vampire Knight : Guilty is one of those series that makes me want to stop watching deep animes and stick to silly romance animes where the ending is always happy. The first season was awesome, but the part 2 was a let down.
[spoilers]
What is the point for the ending? The ENTIRE series revolved around a certain goal. The school, the teachers, the bonds, the story itself had the same goal. Yet with the ending given, It completely makes no sense. 10 hours of episodes spent focusing on one goal, co-existence amongst all groups, yet zero's actions at the end doesn't do anything for that goal.
The entire series filled me with a sense of suspense and anticipation on what was to come. Could have been rated really high, but IMO the ending destroyed EVERYTHING that the series worked for.
