It is certainly a step-up from Vol. 1 which was all over the place, messy with the appearance of numerous villains and cameos from The Flash and Superman. It was kind of fun, but over-saturated and sloppy. Vol. 2 has only one villain - Scarecrow!
I am guessing Hurwitz is a big Scarecrow fan to use him again. You get Scarecrow's origin in this - showing why he is the way he is, and yeah it is a bit disturbing. We really get into the Scarecrow, I dare say this is more about Scarecrow than Batman here. I was never of fan of this design of simply Scarecrow clothes, I felt some of the other versions outside comics work better - like The New Adventures of Batman with the Leatherface look or even the appearance in the Arkham City game. Here, it is pulled off quite well because that burlap sack mask and stitched mouth are just so unsettling.
The art is great as it is dark and realistic, reminds of Neal Adams... almost. Watch out for what Batman does to Scarecrow.... yikes!!!
I wasn't entirely interested in this Natalya character, for that case why should we or even Bruce? We all know how it will end eventually. However, I am glad there was no White Rabbit - none. I couldn't take that "thing" seriously!
The only main problem was the read as I felt the pacing was odd with little to no breaks. If this were to be a DCUA movie it would feel more like a long episode than an actual movie - if that makes sense.
If you are a Scarecrow fan certainly pick this up.
