Some background first: A young Go Nagai (Devilman) initially worked with the creator of Cyborg 009, Shotaro Ishinomori as an assistant for about 2 years before his own professional debut. As such, Nagai had high respect for the legendary artist. This collaboration is born out of genuine love for both series.
On the surface, this might seem to be just a simple crossover between Cyborg 009 vs Devilman, but it's more than that. It actually involves a plot involving high teens cyborgs (Cyborgs that were made after 0013) that are unleashed upon our heroes by Dr. Adams. Add Devilman and co to the mix, and you have a completely original story with completely original characters, and yet the OVA still manages to insert itself into both manga's canon, without hurting each other.
The art and animation is crisp and clear as day. It has a few QUALITY moments, but overall, the production value was good.
Sound was good too. The opening by JAM Project is particularly a joy to watch and listen to, , but the marvel-like ending was amazingly done. It was essentially a montage of scenes taken directly from the source material (The manga of both Cyborg 009 and Devilman).
This was one of my highly anticipated anime of the year, and I wasn't disappointed.
However the only negative thing I could think of is that this series was made for the fans of the original comics, and its appeal might be lost on newcomers to both franchises. That said, if you've never read Cyborg 009 or Devilman, I still suggest you do give it a try if you can find a subbed copy. (Unfortunately, the anime still is not subbed as of 2015)
