Can't say I like how different they look than their manga (or manwha?) counterparts. The art was quite a bit more unique than your usual Japanese animation. Keita's hair style isn't even the same.

I don't like how they changed the beginning either and various things. Keita changed to a boring angsty High School student? DO NOT WANT. I'm friggin tired of high school students. It was a nice change to have a main character that's working and out of school (the real premise). No Akane introduction? Feh. They completely took out the humour, added a lame new character (Yeah, I'm looking at you evil looking megane-kun). The fight and atmosphere failed miserably to capture the same amount of desperation/anger/grief the manga did. There's an utter lack of any emotion at all except Keita's boring stoicism.

So far for me this is a HUGE fucking disappointment. Hopefully it gets better, but I won't keep my hopes up. For those who haven't read the manga they might find this decent or average I guess, but this could've been much better than just passable.
