The series is available on Crackle.com to stream, but I only saw season three available. Hopefully that changes because it's Sony's own streaming service.
I noticed a few mistakes with this review so I though I'd just hit a relatively big one. Section 13 was a law enforcement agency whose job was to deal with international crime. As a result Captain Black didn't believe in Magic until the end of the first season. As a result of mentioning magic to his superiors, the Dark Hand case was reassigned to Section 12.
