I finally got a chance to watch it this afternoon, I liked it so far although I'll have to see more before I can say whether or not how good it really is. I recognized some of the game music as well, then I immediately thought to myself, "where is my god damned DLC?"
The art direction is a little weird, wtf is up with the 15-year-old Bruhl patrolmen, but they did try to keep a little bit of the watercolor effect from the game. Though like you mentioned Lynk, the game already had anime scenes, dunno why they didn't just go with that art style. The only real concern I have is that the anime will be easily predictable since I have played the game. I can't remember exactly but the anime is scheduled for either 24 or 26 episodes, and the game was broken into 18 main chapters, plus some other stuff on the side. So if the anime follows the game closely it's pretty easy to see how it is going to break down. However, the show did take some liberties with the story from the game, which can be good and bad, so I guess we'll see how it goes.
Also, I really liked the ED, little chibi VC characters, thought it was hilarious, Selvaria cooking lulz and by the looks of things, it appears that Marina <3 <3 and Jann will be in the show, awesome! I did notice the distinct lack of the Arcadia characters, Vyse!!
