Well, I'm a big fan of anime and I really want to talk about my favourite anime, Ahiru no Kuwakku, also known as Chiisana Ahiru no Ooki na Ai no Monogatari Ahiru no Kuwakku. It's the best animay I have ever seen. Just the opening alone (Link for reference) is a masterpiece, that only could be made by Veen-sama. Everytime I hear it, I can't help but cry, so beautiful is it. For the filthy casuals who can't speak Japanese (jeez, these guys don't have culture): it's about splashing in water. It is really poetic.
But let's get to the most important point: the story. This story wasn't afraid of offending filthy casuals. This story told the truth. The truth about society. And this is in a fricking komode-muke anime! If only the children shows of nowadays could be as educational as this. Nowadays we live in a society, but back then, the Japanese where teaching children to be critical of our society. Another proof of our society being shitty. If I only could turn Japanese one day and fight with kat and ana with katana's. But let's stay on topic. On to the final verdict:
The final verdict
9/10. Just watch it. Without dubs. (I'll allow subs for the ones who haven't mastered the wonderful Japanese language). The only flaw it has is that it's based on the inferiour Dutch culture. If you only could remove all traces from that shitty culture, I would even place it higher than Cory in the House! (PS: Winnie Wana is the best waifu). (PPS: Dolf de Kraai is the best husbando)
