Saw the first episode a few days ago.  I'll try to get the second one soon.

Impression: interesting idea I guess, but I think it'll be hard for the writers to keep it up without some flaws in the plot line.  A little bland (the girl getting run over was kinda expected, but when it actually occurred, it was kinda double you tee eff?-ish).
Will be interesting to see how it develops though.

Oh, and yeah, I haven't read the manga (so for those that have, don't spoil anything >_>).
