(a) I was pretty sure it was all going to end in tears (see also: Wolf's Rain)
(b) As each successive episode aired, it had me asking, "What the fuck is going on?!"
(c) It's kind of derivative, like that Avenger thing about Mars or something and then no one could have kids and WHAT WAS UP WITH THAT SHOW?
KIBA is about a kid named Zed who is kind of an asshat and then he is transported to a Magical World (TM) with magic, where he is still an asshat. He also has a super powerful spirit named Amil Gaoul who is awesome and kills things but mostly it's about Zed and his annoying uke brainwashed friend Noa, who is so incredibly annoying and brainwashed he spends a good deal of time contributing to a false sense of dramatic tension by murdering people because... um, someone told him to? It's kind of like Miaka and Yui, if Miaka was a power-hungry jerkoff with absolutely zero social skills.
But they are BEST FRIENDS AND YET ENEMIES.
It gets to a point where they're constantly introducing various half-explored characters and countries and then something happens and everything explodes, but then for some reason Zed (who goes through 51 episodes and is still, somehow, an asshat) merges with Amil Gaoul or something. I watched a full half of this series and I still have NO IDEA WHAT IS GOING ON, which I guess happens a lot when you mix together a bunch of things you liked from other cool anime shows but actually have no idea what you are doing.
Stop trying to blow my mind, Japan! It never works!
