The art direction is as good as ever as the scenic art always captures what a fantasy virtual world might look like overall this is an aesthetically pleasing show to look at. Seeing some returns of GU characters also made for a nice mix of World R1 and World R2 styles and features.
I really do enjoy the new style and the new characters are fun to be around. Now we have a female version of Kite and Balmung and a BlackRose with longer hair. Animation quality looks high and character arts while reusing avatars from the previous do give a new and great twist on some of Yoshiyuki Sadamoto's early designs. Animation and art wise Quantum was certainly sporting production values lacking from some previous installments and to Kinema Citrus' advantage they came in on a much later installment to be given a full budget and effort.
While mixed feelings of Kinmea Citrus taking over from longtime.hack// animation house Bee Train I was wondering how a new studio would take a new anime and I can say it's a fun and entertaining watch sure to be accessible to newcomers but may be a bit of a turn off for longtime watchers such as my self. I've seen every anime installment out there and I was actually excited for this. hack//SIGN it's pretty safe to say I'm quite the fan of the franchise.
