The production value for this OVA is spectacular. The artwork, animation and sound are all "√A1" and while they differ from the actual anime series, it is a good change. I felt immersed from the first opening shot of the city and streets. I was given the sense of atmosphere which I desired going into something Tokyo Ghoul related.
Character development is done well for a 30-minute runtime. However, one thing that bothers me is that Arima is a tad bit "Overpowered" for his age. Most investigators are older, wiser and through experience gain the skill he seemed to show off in only 2-3 scenes. The fights could've been a lot better too. When I think of Tokyo Ghoul, I think of fast paced, glowing characters across the screen where as we only recieve a small amount of that in this OVA.
I respect this OVA more then the anime series but it does have flaws which are not that bad in comparison. "Jack" is a 7/10 in my eyes because of the artwork, decent character development, and really good story arc.
